NNTP Service in Windows NT 4.0 and Windows 2000 Contains Memory Leak:Aug 14

Q: NNTP Service in Windows NT 4.0 and Windows 2000 Contains Memory Leak:Aug 14


The NNTP (Network News Transport Protocol) service in Windows NT 4.0
and Windows 2000 contains a memory leak in a routine that processes
news postings. Each time such a posting is processed that contains a
particular construction, the memory leak causes a small amount of
memory to no longer be available for use. If an attacker sent a large
number of posts, the server memory could be depleted to the point at
which normal service would be disrupted. An affected server could be
restored to normal service by rebooting

Preferred Solution: NNTP Service in Windows NT 4.0 and Windows 2000 Contains Memory Leak:Aug 14

I recommend downloading and running Reimage. It's a computer repair tool that has been proven to identify and fix many Windows problems with a high level of success.

I've used it in the past to identify and fix everything from blue screens (BSOD's), ActiveX errors, corrupt files and processes, dll/exe/sys errors, recover lost memory, Windows update problems, defragging, malware removal etc.

You can download it direct from this link http://downloadreimage.com/download.php. (This link will automatically start a download of Reimage that you can save to your computer.)



As Whitesnake once said 'here we go again on my own...'

Microsoft has released a patch that eliminates a security vulnerability in NetMeeting, an application that ships with Microsoft® Windows 2000 and is also available as a separate download for Windows NT 4.0. The vulnerability could allow a malicious user to temporarily prevent an affected machine from providing any NetMeeting services and possibly consume 100% CPU utilization during an attack



Microsoft has developed an improved version of the Cipher.exe tool, offering an important new option – the ability to permanently overwrite (or "wipe") all of the deleted data on a hard disk

To start, I have Windows 7, on Sony Vaio laptop.

I have been working on the issues with the malware removal team, but now machine looks clean, I am still having issues.

When starting the computer and going to the task manager, I can watch explorer.exe start at about 18K memory usage and then grow constantly until it is running with almost all of the computer's physical memory after about seven min. I cannot get the context menu to show up after a few min by right clicking on anything.

I had been experiencing "freezing" while playing Eden Eternal (an online role playing game) before that, which made me consider malware and seek help here at BleepingComputer. The freezing has ended, last time I played on that machine at least, but now there seems to be some issue with the explorer.exe taking all of the memory. I haven't been using the machine since I don't trust that there's not something running in the background that shouldn't be.

In resource monitor there were "connections" that had "-" for both the name and the PID, but I don't know if that was the malware of if that's normal somehow?

Issue with explorer.exe seems to be limited to only one user account, and not the other one. That is to say that if I log on one of the other accounts explorer.exe behaves normally, as far as memory usage.

We have an ASP.NET and Angular based web application which has memory leak issue on IE 11. Running the same web application on Edge, the memory leak issue is much better controlled. But we have many many computers which cannot be upgraded to Windows 10 at
this time.
My question is, are there any recent service patches for IE 11 which can address the memory leak issue?
Thanks a lot.

It didn't usually do this, but probably after some windows update it started happening. 50+% of 8gb ram used when idle. Task manager and resource monitor doesn't show what is using the memory. When I add up all the services, it doesn't even add up to 50%. More like 15-20% of total ram.
Does anyone have a fix? I've looked and already tried disabling the ndu.sys via the regedit (changing value of start to 4). It didn't work.
If you don't have a fix, perhaps you can guide me in trying to identify the problem.

Google Chrome browser, along with their extensions, are responsible for excessive memory consumption on Windows OS.
As the Chrome closing in management tasks, be observed a significant reduction in the use of memory (seen but not captured).

Hi everyone.

I'm not experiencing this problem all the time - that's what I find weird. I've googled a lot, and I see people having the same problems. I'm under the impression that this is not a Win8 problem, but rather an Intel or memory management problem. In various threads on forums, people are disabling a memory management tool called intellmem.exe, but I can't find anything similar in my services.

Here are some of the threads I've been scowering:


This obviously helps Samsung-users, but how do I solve this problem?

Be kind and request any other screenshots you'd think to be helpful. My memory uses from programs (i.e Skype, Chrome, Spotify, Steam) doesn't even add up to a fraction of the used memory.

Okay, so for almost 2 years I had this weird issue and now I give up.

For some weird reason I have occascional "stuttering" when I work with some application (Aero enabled) be it text editr or browser. It usually happens when application was active for some time, around 10 minutes and withing these 10 minutes I did
not switch it to anything. It feels like if you have VSYNC in game enabled but it is double buffered and when your FPS dips you have this continous annoying stutter along with tearing.
The interesting part is that if I win+D (minimie all windows) to desktop and switch back stutter is gone... until it appears again. Due to this annoying reason I'm inapable if using Borderless Mode in fullscreen applications.

I don't see anything special that would hook up to DWM/windows and can cause that, my active software/drivers are pretty scarce and limited. There has to be explanation for this issue but I'm failing ot isolate the cause.

if anyone has any ideas I'd appreciate it

Hello there!

For a week or so now I have had to deal with my memory problem. I have 8GB of memory and the process shows as "System" was taking nearly over 1GB or sometimes 1.5GB for an unknown reason but this only happened when I was on it for extensive periods. I have now fixed that problem however there is still one more memory leak.

This memory leak however, is not cause by a program, i checked my process list and I saw Chrome taking the highest amount of memory being 250MB. However when I go on my performance list I saw 7.5 - 7.7 GB leaving around 400MB - 200MB free but it is not a process taking the memory. Can you please help me with this.

Hello, about two weeks ago I started to have a memory leak, unfortunately right around the time wildstar came out. Just leaving my computer idle the memory just keeps piling on, to the point that if I leave it on over night and wake up the next morning, it's idling at about 90% usage and a constant 30ish% on the cpu.

I figured it was a virus, although I haven't gotten one in years, so I ran malwarebytes and a couple of different antiviruses and nothing came up. So I thought it was bad memory, bought two new 4gb sticks and through them in, and exact same thing happened even on 16gb, it's now taking up 11gb of ram just idling, and resource monitor shows that barely 3gb are actually being used. The only odd thing I noticed is that svchost seemed to be taking up a ton, but nowhere near that much.

Really unsure of what to do aside from system restoring, but I would rather know what this issue is and get it fixed then do that. Any help at all would be fantastic. Below is a link to pictures of my task manager and resource monitor.

I believe I am experiencing a memory leak of some form...at least that's the closest I can come to a description of the issue.
My physical memory usage goes up...way up...sometimes close to the full 8GB I have installed. When this happens I experience sluggishness and problems opening or closing windows.
I am not a power user...I am not running any memory intensive applications, that I know of. Right now I have 3 tabs open in Internet Explorer 10 and my usage is at 6.81GB of physical memory.
When I start my computer it doesn't use more than about 2GB but over time the usage climbs. My computer has been up for nearly 5 days now and the only application that I have personally used in that time is Internet Explorer.
I have BitDefender running. I have MalwareBytes running. Neither application is actively scanning as I write this. Neither program indicates infection.
I've read various complaints on the web and followed some of the advice given to others.
I ran Disk Cleanup recently...say the last 2 weeks...and it currently tells me I can only gain 119MB if I run it.
I checked Disk Defrag...I am 0% fragmented on my Raid-0 system and most of my 1.7TB of disk space is free.
I disabled startup programs using MSConfig ages ago.
Nothing I am running should account for 6.81GB of memory usage and sluggishness.

Hi i'm posting about Winodws 7 Memory Leak. I know the issue has been posted i have read many posts and it still hasn't helped me. I've had memory leaks for quite a while i have 12GB installed and when looking at task manager 9GB is available, although the
amount of free memory drops to 0 when i am transferring something. I recently re-installed windows 7 a fresh install formatted my harddrive etc. I'm still facing the same issue when anything is being transfered the memory drops down to 0 rapidly. The only
thing that fixes this issue a Memory Management Tool.
So now i'm just wonder is there a permanent fix to this issue or would i have to keep using the program that i have?
Because it was a nuisance to re-install and i still am putting all the stuff i had back on. I know that there are alot of people who are getting similar problems. The memory leaks happened as soon as i got on windows 7 installed many updates and same thing

I'm having an issue with what appears to be a memory leak since I've upgraded to Windows 10. Leaving my computer on for any length of time reduces the performance and responsiveness of my computer overall. I've tried using poolmon.exe to see what is using up so many resources and the tag that stood out at the moment was "Thre". When I search for this tag using findstr in cmd.exe it gives me a mile long string filled with gibberish and various characters. I reloaded poolmon to get a screenshot and now I'm getting different results. I'm at a loss here. As I type this post, my Non-paged Pool is sitting at 11 GB. I've already tried a registry hack where supposedly changing the value in HKEY_LOCAL_MACHINE\SYSTEM\ControlSet001\Services\Ndu\Start from 2 to 4 was supposed to fix memory leaks. Obviously not in my case.

Hi there,

This is maybe the wrong section, but I did not know which one to pick:

I experience issues when I open directories with big HD movies in it (around 4-10GB). The media player loads fast (VLC, KMP, WMP) but the video never starts.
After 5-10 secs, my computer starts to run very slowly, I figured out that it was caused by page faults. Indeed, my memory usage goes from 10% to 97% (I have 4Gb, x64 WIN7) in 10secs.

Even though none of the process in the task manager shows a usage of 3.5Gb, I figured out that killing Explorer.exe releases the memory instantly.

This problem avoid me to play HD movies without killing explorer which is very anoying...

Does any one knows how can I deal with this issue?

Thank you!

Since i've upgraded from Windows 8 to Windows 8.1 on my laptop (Lenovo G500S)
I've been getting errors and BSODs while playing games. This are mostly games which use over 1GB of RAM (League of Legends, Chivarly Medieval Warfare and Red Orchestra 2) it gives the error: Please shutdown programs to prevent loss off information. (something in that direction I have the Dutch version.) It basicly tells me that I do not have enough RAM left to run the game. I have 8GB of RAM in this machine with a Intel HD 4000 GPU and a GeForce GT 720m. After I ignore the memory message and keep playing it will blue screen giving this error: DRIVER_IRQL_NOT_LESS_OR_EQUAL (igdkmd64.sys)

I have no clue what to do anymore, I know it has to do something with Intel kernel. I've been looking all over the internet for a fix but can't find it anywhere.

I have uploaded a analysis of the BSOD with a program called Bluescreenviewer, you can see the BSOD's i've had and what it caused.

I was wondering if anyone else has noticed extremely high RAM usage when using windows 7's chkdsk.  I've used chkdsk on the same USB flash drive on my XP, vista, and 7 machines, and the memory usage is as follows:xp : 20 - 30 MB (Depending on stage)vista : 2.5MB7 : about 25MB per second running (e.g. after chkdsk has been running for 10 seconds it will be using 250MB, after 2 minutes it will be using 3.0GB)I am monitoring memory usage using task manager.  I actually have two machines running windows 7 7100 release candidate (x64) and the I noticed the problem on both.The problem is easiest to duplicate if you run chkdsk on a drive other than your OS drive (so you can actually have task manager open while it runs as opposed to running after a reboot), and if you run a check that will take a long time.  chkdsk /f on a large hard drive works fine, or chkdsk /r on a smaller hard drive will work as well.  It doesn't seem to depend on which stage it is in - the memory usage balloons during stage 2 of a chkdsk /f on a (full) 1TB hard drive I have, and it happens during stage 4 of chkdsk /r on a half-full 32GB USB flash drive as well.I would be interested to see if anyone else can duplicate this.

A:Windows 7 chkdsk memory leak?

Maybe it's not faster but somehow more accurate or more likely to correct problems successfully?  Without looking into the implementation, it's impossible to know what's better, or really even
if anything's better, but it's been stated it's allocating this memory by design.  We have no choice but to live with it.  There are a LOT more important glaring problems in Windows 7.

When you say "it's been stated it's allocating this memory by design" are you referring to the following quote from

"from their perspective the memory usage was by design and was a specific Windows 7 change for this scenario (the /r flag grabs an exclusive lock and repairs a disk and so our assumption is
you’d really like the disk to be fixed before you do more stuff on the machine, an assumption validated by several subsequent third party blog posts on this topic)."
He states that the behavior is limited to the /r switch but I've seen it with the /f switch - the memory usage increases just as quickly, the only reason it doesn't get as high is because chkdsk /f doesn't take as long.
It might be nice to get a little more information from someone on the "file system team", but if they truly have looked at the issue as he stated in the blog, then it either isn't a bug or it is but it would be too much work to fix when weighed against the

Hi guys. I have Windows 10 on my work computer dual-booted with our standard Windows 7 image. I'm mostly testing out how well it works and for the most part it's pretty smooth, aside from not having RSAT yet.

Unfortunately today I noticed that my RAM usage was really high at 80%, with only XenCenter and a few tabs open in Microsoft Edge. When I looked at Task Manager, it showed that System was using 2.4GB (40%) of RAM in my 8GB system:

I turned to the Windows WDK and poolmon to tell me what was using up so many resources, per this link:

That brought me to tags "smNp" and "smBt".

If I then open up a command prompt, navigate to drivers and do "findstr /s smNp *.*" or "findstr /s smBt *.*" they both point to rdyboost.sys.

I have no USB devices plugged in to my system, the only non-internal disks are just a CD in the DVD drive and a mapped network drive.

Did I go wrong somewhere? Why would a USB device performance technology be consuming such a large amount of RAM on my system? I'm sure once I restart it will go away, but I'm worried I won't be able to keep using W10 if I'm running into memory leaks like this one.

In the last week or so, I have to reboot my pc almost every day because the RAM usage gets up to 93% and I can't do anything, even launch taskmanager. When I've caught it before it was too full, I saw that almost nothing was listed as using RAM (system was at like 80MB). Essentially, RAM is "in use", but the use is not explained by taskmgr or perfmon.

I'm prepared to learn that it's a BIOS or mem controller issue, but it never happened in several years of XP and Vista on the same rig. Also I see I'm not the only one with the same issue on Win 7 64bit:

Blaming windows would be the first reaction, but is it warranted? I have no such problem, with 64 bit. Maybe, you have a virus, or maybe all your memory is not recognized. There are a lot of areas to look into before we can assume that it is windows.
Many times the A/V is a memory glutton. Other times other things are going on in the system, indexing, or a virus scan. All things to think about.

Over the last few weeks I've been noticing the memory usage on my computer increasing slowly over time as the computer stays on. I am running Windows 7 Pro 64-bit with 4GB memory and am running both Avast Antivirus and Malwarbytes and neither have found anything suspicious.

While looking at my Windows processes in task manager, I noticed that one process, scan2pc.exe, has almost 18,000 handles, way more than any other process. In addition, some of my processes keep increasing in their memory usage. nvtray.exe seems to be the biggest culprit, starting out at around 1,000K but if I leave my machine on for a few days will balloon to over 500,000K. Could malware or a rootkit infected my machine? I'm not blue-screening or experiencing crashing programs (yet), but the memory leaking is certainly bothersome. Any help would be greatly appreciated!

For the last few months my I am experiencing a large memory leak with svchost.exe (the one associated with process nsi). Operating systems is Windows 7 64 bit. The memory grows over a 1 week period to use most of the 8gb of available RAM. Only solution so far is to reboot and then it just starts building up again...help!

Thanks Much!!!

Hi all,

I'm experiencing a problem in the office's server since I installed Windows 10. The problem is a well-known one with LSASS.EXE, and I've found that it's docummented and there are patches for Windows Server 2012, Windows 8.1 and Windows 7:


My problem is there is no information about this problem on Windows 10.

The computer works like a charm... until lsass.exe starts taking more and more RAM. When it takes the whole 16GB the computer works awful and has to be restarted.

I attach some screenshots:

Memory Usage:


The computer is a server but has no active directory, it's a common lan with four computers and the server has (among other functions) a ERP that uses SQL 2016 with a database.

Since I saw a reference to Named Pipes I tried to disable in "cliconf.exe" but it didn't solve the problem:

I Found some information about memory leaks in windows 10 (not related to LSASS but "Windows Network Data Usage Monitoring Driver", so I modified registry in this way:

Navigate to Computer\HKEY_LOCAL_MACHINE\SYSTEM\ControlSet001\Services\Ndu and then from the right hand section of the window double click Start in order to be able to edit the Value data setting. It will probably be 2 but changing this to 4 will disable the ndu.

Server specs:

-i7 Haswell @4,5 ghz
-Asrock Z97 extreme4 motherboard
-16 GB RAM DDR3 2400mhz
-Integrated VGA
-Raid 0 SSDs

My C: drive is 3GB away from "disk full" It's a 750 GB disk. I am on Windows 10. This is especially remarkable, since I store very little of my "live" data on the computer -- almost everything is on USB drives and cloud.
How do I find out where all the storage is being used?
One possibility is that I create and delete accounts on this computer fairly regularly. When I delete accounts, I sometimes get the message "Cannot delete account for a user that is logged on" -- but that account is logged off, and it gets deleted anyway, so I haven't worried about it. Might there be files that aren't getting deleted?

This is NOT the "100% disk usage" thing with several other articles, relating to Windows Search and Superfetch -- the disk is not busy, it is full.
Please start your answer right at the beginning of the instructions -- I used to be a very sophisticated programmer, but lost hold of Windows somewhere around Windows XP. I removed all the Charms and other Windows 8 crapware. Please start your instructions to me with the START button or with WindowsKey/R or something else that is unambiguous and not likely removed.
Thank you.

if I leave my computer unattended for an extended period, the RAM usage climbs up to around 80% and leaves me struggling to use my computer when I return. It is not one process that causes this - but nearly everything, Chrome itself can get up to 100,000 KB memory usage, along with every other process on the computer. The only way to resolve it is to restart my PC.

This doesn't occur if I stay on the PC and do not leave it unattended - but for reasons I cannot fathom, if I walk away for 15-20 minutes, it'll start to hog the memory and make it unusable again.

I've been told it's because of the Superfetch service - but upon disabling it, there was no notable increase in speed. My other Windows installations work fine - as does Ubuntu, so it doesn't appear to be a hardware issue.

Any suggestions as to what to try?

Hi nocturna99

Try Process Explorer to double-check your background processes http://www.sysinternals.com/Utilitie...sExplorer.html
And AutoRuns to double-check your Startup processes
And Rootkit Revealer to try & detect if a rootkit is involved

If the change is recent enough, you can always try a System Restore, to a restore point from before the trouble started.

If you haven't visited Windows Update recently, make sure to try that, too - as there might be a recent patch that helps your situation.

Best of luck
. . . Gary

[P.S... . let us know if you find a rootkit present - and would like strategies for recovery]

I am running a relatively new installation of windows 7 enterprise 64-bit and am getting intermittent memory leaks in svchost.exe (running -k LocalService). Just to rule out malware/viruses, I rebooted my machine with Kaspersky rescue disk and did a full scan. Zero problems. I've also done full scans with anti-malwarebytes and superantispyware and they only found cookies. So it's definitely not a spyware problem I don't think.

I have only a handful of services running under this PID:

WdiServiceHost - Diagnostic Service Host
nsi - Network Store Interface Service
netprofm - Network List Service
FontCache - Windows Font Cache Service
fdPHost - Function Discovery Provider Host
EventSystem - COM+ Event System

I am pretty sure it has something to do with the networking services. The last time my memory went to 99% utilization, I disabled my ethernet adapter from the network and sharing center and immediately CPU usage maxed out on all four cores and the machine ground to a complete halt forcing me to hard power cycle. In addition, any attempt to stop those services once memory utilization reaches a peak results in either "process didn't quit cleanly within a reasonable time" or "other services are relying on that, you can't stop it" messages (those aren't the exact errors but the next time it happens I will get the exact text)

Dear Friends,
We are facing a problem of RAM utilization increase(memory leak) on our system with 14 PCs.

4 PCs are working with Windows server 2008 R2 SP1 and 10 with Windows 7.

We released that the RAM rise is due the antivirus recent version ie. Symantec 12.1.5.

But when we searched on net we found similar problem being faced by other people please see the link:

Solution for the same is given as a patch for Windows https://support.microsoft.com/en-us/kb/2885980 .

We have installed the patch on one of the Windows servers machine for trial purpose and found that the patch really worked in our case. RAM increase has stopped.

Then we installed the patch on Windows7 machine but the RAM is still increasing in these machines. The tag name we got from server machine is Fwpk.

But for Windows 7 machines we are unable to identify the exact file or drivers which is causing the RAM rise.
Could you help us on how to find out the exact root cause for this rise?

Thank you,

Thanks and Regards, Shailendra:- Keep Smiling

I'm having a problem with a possible memory leak on my Windows 8.1.

After few hours (2-3), the used memory goes to about 95% and my laptop slows down a lot and becomes almost impossible to work with. Using Lenovo Thinpad Edge E 531.

Task manager and RamMap show high Paged Pool usage

Using poolmon, I was able to find the Tags causing it.

Using "findstr" on the SeAt, SeTd and SeTl tags doesn't find anything. When used on the Toke tag, it finds several pages of text with vhdmp.sys (vhdmp.inf) highlighted.

Using the strings.exe utility on SeAt tag, I was able to find theese two:

C:\Windows\System32\drivers\NETwew00.sys: utilPanP2PBuild_NoticeOfAbsenseAttribute
C:\Windows\System32\drivers\NETwew00.sys: prvhPanCnctWAC_BuildDeviceAdvertiseAttr

Searching for the other three tags results in over 100 lines.

A:Windows 8.1 memory leak - unable to find the culprit

I tried a different approach. I found an article about faulty bluetooth driver on Thinkpad laptops, so I disabled it and for now, the paged pool memory seems to be ok. Toke tag is staying at cca 3MB.
However, the non-paged pool jumped to 1,3GB. The biggest contributor is ECMC tag with 1GB. Findstr shows excsd.sys, which is express cache driver. So I'll look into that.

The memory usage is still pretty high, but at least I feel like I'm getting somewhere now.
This RamMap shows usage with only Chrome browser on, which takes about 700MB in total at the moment.

Hey, so over the past few weeks my computer has been getting random CPU spikes, where there's only 3% being used but it says it's using 100% of it and freezes.

On top of this, Windows Update seems to be taking up a lot of memory - and I mean insane amount, I've seen it go up twice as high as in this screenshot. For now, I keep the service disabled rather than cripple my machine, but when it's enabled it's always when it's "Checking for new updates"

After further investigation it seems like both of these problems are caused when I am doing something over the internet. The CPU problem happens when I'm downloading games off of Steam (as well as random things as well, but it always happens in that scenario) and the memory problem always happens when windows update is checking for new updates.

How do I fix this?

Hey guys,

I have no programs running, just chrome with a couple of websites. On my previous pc with windows 7 i've never had the memory use more than 5 GB just for chrome. Also, the paged pool seems to fill up the longer I use my pc. I've read numerous threads with people saying that it is normal for a pc to use all the RAM because otherwise it's useless RAM. But I don't really believe that something like this is normal. In most threads people talked about a memory leak in the non-paged pool.

I find it also very weird that when I look at my processes they just don't add up to the 5 GB in use. Using rammap or process explorer doesn't show annything at all.
Here are my specs:
Lenovo B5400
Windows 8.1 64-bit (6.3, Build 9600)
Intel Core i5-4200M CPU @ 2.50 GHz (4CPU's)
8192MB RAM

I'm having real problems with League of Legends, I just get too much lag when I play. I have a constant 40 ping so that's not the problem, my fps is 60-70 so that's not really bad. But I just get these random stutters every few seconds. Also when I browse my pc is just acting too slow for it's specs.
I hope someone can help with this problem as I am a noob when it comes to computers. I paid about 700 euros for this laptop and I find it sad that I this stupid problem. I've already disabled superfetch and I really don't want a link to another thread as I've read every single one of them and I'm getting nuts


A:Windows 8.1 - Memory leak problem in paged pool

Hello SebaaVH,

You appear to be one of those affected by this Google Chrome bug that only affects "some." Now, since I don't know if they ever fixed it (I don't use Chrome), I would suggest trying a different browser (i.e., Firefox or Opera) to see if that fixes your issue. Now, some have stated they fixed their issue by clearing their browser cache but that would be just a band-aid IMHO:

Massive memory leak, though memory usage does not show for GC in task manager:

Regarding your League of Legends issue, I don't play it myself but your issue (or something similar) has come up several times quite recently and, if you do a Google search for that issue, you will find tons of people having issues when playing it online. You might be better off seeking assistance at a gaming forum for that specific issue IMHO.

Good luck.

I have been living with some issues for the last 6 months and need help to get the problem figured out. I believe I was infected by a virus of some sort on June 4 2010 that has stuck around despite NIS and Malwarebytes scans. Any help would be appreciated.


Since the infection, I have not been able to automatically or manually update Windows via the Windows Automatic Update tool or by manually going to the Microsoft Update web page. Each time IE7 opens, I get error number : 0x80072EFF "The website has encountered a problem and cannot display the page you are trying to view. The options provided below might help you solve the problem". I can get onto the internet to any other site. It is just the windows update site that seems blocked.

I have a svchost process that grows with time until it is using 500+MB of my memory and usually ends up pegging the CPU to 99-100%. I have viewed the process using Process Explorer and note that the thread start address that peg the CPU are ntll.dll!RtAllocateHeap+0x18c. If I kill those threads, I am able to work on the computer for a little more time, until the threads peg the system CPU again. But, the memory usage is concerning me as I need to utilize that memory for my work, and I get programs failing because of memory allocation errors, which I attribute to this svchost issue.

I will periodically get redirected to other sites while surfing. This happens sporadically. It may be a day or two betwe... Read more

That's not good that you let this issue persist for six months. There's some things you should try here. For one, download DR. Web CureIt. Do a google search for that and it should pop up. It's probably better if you run it in safe mode. post back the log when it finishes. note that this scan will take a long time. Make sure that when presented with options, you select cure and then move incurable. After that, look for Kaspersky's free virus removal tool 2010 and run that. That should find some stuff if anything will. kaspersky has very strong find and removal capabilities. Finally, run an online scan with Eset online scanner. You can find it at eset.com/onlinescan. Post back the three logs in your next reply. Hope this helps.

Good luck,

Just got on the computer now, and suddenly everything seems to be slow, I checked the memory and found out that some program is using 94% of the memory, when I was looking for the program I found out that no program is using that amount of memory, 200 at most.

I downloaded RAMmap to map out the memory, and found out that about 94% of the memory is Nonpaged Pool (unallocated?)
. Please see the image below:

As you can see the memory leak clearly.
