Everyone in C:\Users Security Tab?? Is that right?

Q: Everyone in C:\Users Security Tab?? Is that right?

Hey guys, I have windows 7 and set up Homegroup. All the folders I share additionally to what Homegroup is sharing have EVERYONE in the Security Tab enabled with all Permissions checked!

Now I also realised that C:\Users has in Security Tab has EVERYONE with Read & Execute - List - Read activated?

Is that the default option?

And is it normal that every folder I share in Homegroup gets EVERYONE added with all Permissions?

Preferred Solution: Everyone in C:\Users Security Tab?? Is that right?

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.)

A: Everyone in C:\Users Security Tab?? Is that right?

If i read your post right you are talking about Share Permissions and not NTFS permissions.

If this is the case, the is normal. When looking at what access a user has when accessing a shared folder, you combine the share permissions and NTFS permissions with the least priviledge taking priority.

For example, if user John has FULL CONTROL permission to the USERS share but has only READ permission for NTFS permissions on that folder, then John can only read.

Hi all

I just realized that when i installed windows, I only had an admin account. I created a normal user account, but all my programs are installed for the admin user.

How do I make an existing installed program available to my 'normal' user?

Also, how do people secure their machines? Meaning, do you run malware, firewalls, etc, and if so which?

thanx in advance...

Hi guys,

Two days back I saw that an outsider who was previously company employee came with his own notebook and he tired to access the access point whose security code was known to him but his user name and password was disabled form the sensys domain. One more risky thing was that the user can access the wireless network i.e. by access the access point from outsider the company.

In the first phase to protect unauthorized user form accessing the access point of our company I have asked the IT to change the security code of the access point and do not share it with the notebook user and provide the code manually once on all the machines.

But I want more then that, I want that only notebooks which are authorized can be accessed and authenticated on our domain and any other notebook which is not listed should not be authenticated on the our domain.

Please provide your feedback in this regard.

Hello.Im using comodo firewall and panda free av.

Panda Free AV settings: default. I also have the panda toolbar.
I have tested this combo a lot and the system remained clean.
I picked panda because its very light. I tried Qihoo but it was heavy and i saw an article about stolen data or something whatever. So i deleted it and installed panda.
Althought with cruelsister's settings u dont really need av but i wanted one
PS: In my opinion Panda is underrated product BUT if you try it for yourself you will see its pretty good.

I'm new to the whole security world, and I barely know the difference between worms and Trojans. I saw a similar topic from September but it was more pro-oriented.
Currently I have 3 AVs on my device, I know it's wrong from both security and performance points of view. So apart from a good real-time AV, what would you install on an average user's device? Firewall, Sandbox, on-demand antimalware (MBAM or Emsisoft), MBAE, Bitdefender USB, ("HIPS" keeps coming up in conversations here, I have no idea what this means)...? And when professionals here talk about adblock, do they mean the browser extension or something else?
In a descending order, every internet user should have: (and please don't say just Microsoft security essentials and Windows firewall)
Real-time AV
On-demand antimalware
and then what?

A:Basic security for average users?

Well, it's a difficult topic actually. Take a look at these threads below to have a clearer image.
For an average user, sandboxes and HIPS are a no-go. They need quite some configuration and proper knowledge to respond to alerts.
Windows Firewall would me more than enough for protecting your network from inbound connections.
A simple free AV would be good for real-time protection (like Avast or Avira) or even Windows Defender that's built-in from W8 onwards. Some anti-exploit protection would be a good addtion, but chances to stumble upon something like that are almost non-existent.
Adblock refers to what you mentioned in your post. Exactly.
Now, a couple on-demand scanners (MBAM, HMP, EEK) would complete the puzzle.
But all of the above would be worthless, if not accompanied by common sense and safe browsing habits.

Hi Folks,
Most of you may already know this who use the unlocker utility (and I find it rather handy). Well, discovery yesterday, it is detected by some security programs (MSE as Trojan, and NOD32 as Adware in particular), but there is one problem with this detection. I wouldn't call it a false positive per-se, but I'd call it more of a take-away of the user's rights. The only reason that it is detected is because of a clearly optional component that automatically starts up IE and redirects the user to www.ebay.com. What right do security programs have flagging programs due to optional components? I don't understand it, and I'd seriously recommend that the above companies reconsider their decision. Let me know what you here in this community think, and I'll certainly complain myself if you'd like.


A:security, sure, but where are the users rights here in 2010?

Basically your complaining about how they detect certain viruses. They are not gonna compromise just cause it may detect something you may deem as "safe". Seriously you should not be so mad at how they detect problems they do not have time to download everything for your convenient and test it. If you want just add it to exceptions or use a different av if your so upset about how they try to protect you....

Hi there.

while I love the chromecast thingy there's a possible security leak - especially if you don't use the new Ethernet connector. The Chromecast will present itself in a WIFI broadcast map allowing possibly an unauthorized user to logon to your WIFI network.

The danger only exists if you have to restart the device or while you are setting it up but beware and ensure your Router has all the logs enabled etc.

Chromecast for the price is a really good device but do check the security implications.

People ignore software security warnings up to 90 percent of the time:

A new study from BYU, in collaboration with Google Chrome engineers, finds the status quo of warning messages appearing haphazardly?while people are typing, watching a video, uploading files, etc.?results in up to 90 percent of users disregarding them...

Researchers found these times are less effective because of "dual task interference," a neural limitation where even simple tasks can't be simultaneously performed without significant performance loss. Or, in human terms, multitasking.

"We found that the brain can't handle multitasking very well," said study coauthor and BYU information systems professor Anthony Vance. "Software developers categorically present these messages without any regard to what the user is doing. They interrupt us constantly and our research shows there's a high penalty that comes by presenting these messages at random times."

For example, 74 percent of people in the study ignored security messages that popped up while they were on the way to close a web page window. Another 79 percent ignored the messages if they were watching a video. And a whopping 87 percent disregarded the messages while they were transferring information, in this case, a confirmation code...

Ok I've been doing this for a while so I thought I'd share it - it will work on any NT/XP machine (probably vista too).

go to start-run,

type "secpol.msc" (without the quotes) and hit enter.

Go to "Security Options" (under local policies)-

scroll to:

Network security: LAN Manager authentication level. Change this settings to "send NTLMv2 response only\refuse LM"

Also change:
Network security: Do not store LAN Manager hash value on next password change to"enabled." Then change your password.

This is important if you have lots of people accessing a computer because it is relatively easy to crack anyones password (including the admin) by using a simple brute force method of checking hash tables.

I *believe* (someone correct me on this if i'm wrong), if you have a password over 14 characters long, even if its stored in the LM hash, a hacker will only be able to get the 14 characters of the password ???

You can also change;
Network security: Minimum session security ...clients
Network security: minimum session security...servers
Set those both to "require NTLMv2" and "require 128-bit encryption"

Anyway, hope this helps. If you are a home user you don't really need to worry about this, seeing as a hacker would need physical access to boot from a CD to crack your password.

Hi all

New user here. I'm pretty good with Windows and computers in general, but can't figure out this new problem. I started worked from home recently, and find myself easily distracted by going online (facebook, etc) or going through my personal files on my computer.

I download an app called Cold Turkey which works well for blocking websites and programs I shouldn't be using during work hours. This is great.

To block myself from my personal files, I installed another hard drive to save my work files on. Then I created a standard user (my work account) and blocked it from accessing my personal hard drive. (My C: drive is separate SSD). I then made another standard user for my personal desktop, and used the parental settings to not allow me to login to that account during work hours. I let my wife create a password for the admin user, which I am not allowed to know, and I only change settings with her letting me into the admin user.

In summary, as it stands:
work user: standard, no access to personal drive
personal user: standard, restricted to login during non-work hours only
admin user: full rights, only my wife knows the password

Now, the problems. I can't install new software under my work user or my personal user without my wife being home to insert the password. This is annoying and unnecessary and sometimes I need to install something for work and I have to wait until later when she's home.

My friend's computer HD developed corrupt blocks and we could not do a restore or repair. I booted off a linux live USB stick and to my surprise was able to get access to all of my friends files and their contents but also to my relief as this meant her work was not lost.
I say surprise because I was of the understanding that these files were only accessible to the account owner but here I was with a linux usb and having full access to those files and viewing their contents. This means that I can so the same with anyones computer? How can this be? Am I not understanding how accounts and security works on Win10 systems. I thought that files and folders belonging to an account could not be viewed by anyone who didn't have the correct password. TBH what happens when someone experiences what my friend did hadn't crossed my mind with regards to how they get back their work.

After replacing the HD with an SSD and installing Win10 I connected up the HD and copied across the users complete account folder to the SSD, viewed it's files and contents and then switched off. Today when I navigate to the user's folder on the SSD everything is gone, vanished?!

So, since the Internet is (sometimes) a beautiful place to exchange knowledge and learn some more, here I am writing these questions.

Let's begin then:
Ok, yesterday I went back home and before going to sleep I decided to surf the web a bit (Firefox with uBlock Origin). It was a stressing day so why not... um, surf some... sites you know what I mean, maybe. Everything was going fine, but then a page opened itself (by a script I think?) when I clicked on the player. It was not a problem, since I was feeling protected enough, but then another one opened with a fake Firefox page asking for e-mail and password and the infamous "click CANCEL to continue". Of course I didn't type anything and I killed the firefox.exe just in case. But in that occasion, a thousand of questions came to my mind. I NEVER and I really mean NEVER took a virus, malware or other kinds of infections in my system (maybe only when I was a kid, without being aware of it). So I scanned my computer with Kaspersky Free: nothing found. Then, for a second opinion, I ran Emisoft Emergency Kit: nothing at all. Also I'm usi... Read more

A:Some general questions to experts about security that other users may also find useful.

Skepticism said:

1. If Kaspersky and Emisoft Emergency Kit didn't found anything, does it mean that my computer is
completely clean or should delve deep even more with other softwares? So if two major softwares don't
find anything, there's a need to scan even more?Click to expand...

An on-demand scanner, whether you using one, several, or a thousand, won't detect all malicious software available in the world. Therefore, a clean verdict from the scanners does not mean that the system is undoubtedly clean... This neither means the on-demand scanners are not useful and that you are indeed infected. The likelihood is that you are fine after what happened and that the system isn't infected, and that it is simply paranoia talking (gets to the best of us sometimes).

You could request for malware removal assistance on this very forum by clicking here. You provide logs which you're instructed about generating and a staff member will check over the logs and determine whether anything is necessary to be done - bear in mind this is not full-proof just like on-demand scanners, nothing stops the logs from being tampered with on-the-go without you being aware. So it goes both in hand really. However once again, the likelihood is this would not be the case.

1a. And if a system is clean, can something infect you online and online only within the browser?Click to expand...

The short answer is Yes, the long answer is No. Or it... Read more

I am considering buying Kaspersky Internet Security in store; is this Kaspersky software version worth the buy?
I am using AVG Free as of right now, and a Kaspersky Anti Virus Trial!

A:Kaspersky Internet Security 2016 - 3 users 18 months

Kaspersky is consistently ranked near the top by anti-virus testing labs. Here's a comparison chart from AV comparatves web site: http://chart.av-comparatives.org/chart1.php?chart=chart2&year=2015&month=12&sort=1&zoom=2.
Pc magazine has a review of it as well. http://www.pcmag.com/article2/0,2817,2460689,00.asp
Performance is important but Another consideration is the usability of the software. Are you comfortable with the user interface? Is it easy to find out if your anti-virus definitions are up to date, configure scheduled scans, etc.

PROBLEM: "unknown Users" are listed in Properties/Security of a folder.

I have Windows 7, 64-bit.

The Properties/Security box of my "C:\Users\[my name]" folder lists two Users called
"Account Unknown (S-1-5-21-879640176-2077098734-2292519611-1001)"
and, "Home Users", in addition to the legitimate Users "SYSTEM", "Administrators", and
"[my name]".

After deleting the computer's Limited Acct, the 2 Users are still listed.

"S-1-5-21-879640176-2077098734-2292519611-1001" is not found by the Yahoo Search
Engine. The Windows folder-specific search engine for "C:" and for "Users" searches essentially
indefinitely. That for the folder named after myself finds nothing.

Especially regarding "S-...", is this caused by malware ? Would deleting either or both of these
Users cause harm ?

A:"Unknown Users" listed in Properties/Security of a folder

Hi -
What are the names of the accounts?

By any chance - TrustedInstaller, Authenticated Users, Administrators, SYSTEM, ...?
Do the additional unnamed users show up on all files?

Do you have any problems accessing the files?

See what happens if you remove the users from one of the files.

Thank You -

A password manager is a software application that helps a user store and organize passwords. Password managers usually store passwords encrypted, requiring the user to create a master password; a single, ideally very strong password which grants the user access to their entire password database. Some password managers store passwords on the user's computer, whereas others store data in the cloud. While the core functionality of a password manager is to securely store large collections of passwords, many provide additional features such as form filling and password generation.

I am using LastPass extension for Google Chrome and it saved me a lot of work and write. At the same time, I allow it to generate unique strong passwords with enough length, up and down cases, numbers and symbols.
For the sites like Facebook, Youtube, MalwareTips and others I visit often I have my own way of creating a strong password with a combination of those letters above.

Well, as you already know probably, LastPass has a nifty option to check your passwords, for duplicates, weaknesses, and if your accounts/passwords were included and leaked in some attacks, and became vulnerable, recommends changing the passwords for them.

All you need to do is :

Log in to your LastPass Account entering your email and your master password
Click on LastPass extension button
Click on Tools and then Security Check

Finally, click on Get Your Score. LastPass will ask you to enter your master pass... Read more

I looked at my folder properties, the security tab on win8 "C:\Users\mike"
I see securities permissions for "Account Unknown S-1-15-21-etc..-1002" (i'm 1001)

Searched the registry, nothing found. Anyone have Idea what this might be ? Thanks !!!

I'm not overly concerned, slightly maybe,,, mostly curious.. might delete it and see what happens after next system image.

A:my users account unknown security, special permissions

I would suggest deleting it.
There is no such user in the valid users selection box.
Running a virus scan would be good.

When Microsoft released the Windows 8.1 Update, IT feathers were ruffled by Microsoft's decision to make it a compulsory update: without it, Windows 8.1 systems would no longer receive security fixes. As spotted by Computerworld's Gregg Keizer, Microsoft is applying the same rules, at least in part, to Windows 7.
Windows 7 users who've installed Internet Explorer 11 are required to install the KB2929437 update. This is the Internet Explorer 11 update that corresponds to the Windows 8.1 Update; it doesn't just include security fixes for Microsoft's browser. There are also some new and improved features, including a more capable WebGL implementation and some additional high performance JavaScript features. If users don't install the update, Windows Update will not provide any more security fixes for their browser.


A:For Internet Explorer 11 users, no update now means no security fixes

I recall the update but didn't realize the implications behind it, probably because IE is seldom used on my computers, was going to open it & see if there are any visual differences.
However IE11 is now freezing & EMET 4.1 is giving a 'SimExecFlow' error. Will sort it it out in the morning.
Or maybe it's better security wise to leave IE frozen?

We use Group Policy Objects (GPOs) to implement security on our Internet browsers. 
When one of our end users needs a ?webex? type meeting for support from a vendor, they click on the link supplied by the vendor to download the necessary executable to their PC (Win 7 mainly, just starting to roll out Win 10).  [Since this mentions
GPOs, I am going to post this in Windows Server > Group Policy, too.]

In Chrome, they cannot download the executable, it gets blocked. 
In IE11 and Edge, they are told it is blocked but after clicking on Retry, (I am assuming the executable has then had time to be scanned and is deemed safe and) has been put in their Downloads folder. 
However, they cannot run it - in Edge, they get no message, in IE 11 they get a Windows Security Warning ?Windows found that this file is potentially harmful. 
To help protect your computer, Windows has blocked access to this file. 
Name:  name.exe, OK?.  Using either MS browser, they then have to go to their Downloads folder (a major hurdle for many of our users), find the executable (another big hurdle), right click on it, select Properties,
General tab, and click on the Unblock button then the Apply button.
Is there any way to use a GPO to eliminate this step?  Or, is there a security setting we can apply to the Downloads folder of the users that most frequently utilize this type of support, not for every download but for say webex*.exe or
bomg... Read more

The problems have been revealed by security firm IOActive – just weeks after Lenovo was found to be shipping PCs with pre-installed ‘Superfish' adware that also left its users open to MITM attacks.
IOActive researchers Michael Milvich and Sofiane Talmat say in an advisory that they discovered the latest “high-severity” privilege escalation vulnerabilities in Lenovo's System Update service, which enables users to download the latest drivers and other software, including security patches, from Lenovo's website.
The researchers found the flaws in February, and have now gone public on them after giving Lenovo time to develop a patch, issued last month.
But while the patch fixes the problems, users have to download the security update to protect themselves. Milvich and Talmat say that one of the vulnerabilities, CVE-2015-2233, allows local and remote hackers to bypass the device's signature validation checks and replace trusted Lenovo applications with malware.
Another bug, CVE-2015-2219, is a weakness in Lenovo's security token system, which means least-privileged users could gain high-level access to Lenovo PCs, laptops and other devices and run their own malicious commands and programs.


A:PC maker Lenovo exposes users to "massive security risk"

I'm starting to like Lenovo products less and less now. They have super good products for the price (specs wise), but security and privacy wise, it seems like they have a lot to learn from.

VPN users are facing a massive security flaw as websites can easily see their home IP-addresses through WebRTC. The vulnerability is limited to supporting browsers such as Firefox and Chrome, and appears to affect Windows users only. Luckily the security hole is relatively easy to fix.

The Snowden revelations have made it clear that online privacy is certainly not a given.

Just a few days ago we learned that the Canadian Government tracked visitors of dozens of popular file-sharing sites.

As these stories make headlines around the world interest in anonymity services such as VPNs has increased, as even regular Internet users don?t like the idea of being spied on.

Unfortunately, even the best VPN services can?t guarantee to be 100% secure. This week a very concerning security flaw revealed that it?s easy to see the real IP-addresses of many VPN users through a WebRTC feature.

With a few lines of code websites can make requests to STUN servers and log users? VPN IP-address and the ?hidden? home IP-address, as well as local network addresses.

The vulnerability affects WebRTC-supporting browsers including Firefox and Chrome and appears to be limited to Windows machines.

A demo published on GitHub by developer Daniel Roesler allows people to check if they are affected by the security flaw.

IP-address leak

The demo claims that browser plugins can?t block the vulnerability, but luckily this isn?t entirely true. There are several easy fixes available to ... Read more
