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.)


Last week I have been messing around with Windows Firewall Control, and have enabled Medium Filtering.
This denies all apps from accessing the internet, unless I allow them manually, one by one.
Is this boring process going to increase my ransomware protection (refer to title)?

PS. Please don't hijack this thread with recommendations of anti-ransomware protection like CF, I already know them. Thanks in advance.

I have been trying to encrypt a folder using PGP 9.0.6 and Cryptainer Secure It 3.1.7.



What's weird is that the folder and the files within it will not encrypt and I don't know why? Further more the folder will actually be missing files. Can anybody explain to me? No, I am not setting the applications to erase files after completion.

PGP Conventional Encryption has worked finally. I tried all the obvious stuff first like closing all non-essential volumes (virtual disk that are created and encrypted by PGP), transferring the files to another drive, etc.

On a slightly separate issue. I did have some data corruption involving an older and separate group of files. However I deemed that to a hardware failure or a OS/Software failure. Figured it might provide valid insight.

Update: Now my PGP conventional encryption, non .exe file generation worked. I don't understand why it wouldn't work? Going to rename the source folder and try again. MY encrypted .exe file generation with PGP should work.

I tried again. PGP conventional encryption and PGP Zip both encrypted fine. I tried creating a PGP .exe file and again it failed and files are missing; why?

A few days ago, I noticed a popup saying computer wanted to reboot and would if I didn't postpone it. I wasn't doing anything, so I went ahead and did it. The windows updates (running Windows 7 Professional 64-bit) applied and I got back to the desktop. Adobe put up a box saying there was an update for it too, so I clicked on it. Before I could start it though, I got a windows box that said "Encrypting File System" and told me to backup my file encryption certificate and key. After some searching on google with a different computer, I found that this sometimes come up even if you have never encrypted anything as I have not. So I went ahead and let it save the key to a flash drive. I did the cipher /u command to find if any files were encrypted. It found thousands of files in 7 directories. Mostly pictures (.jpg) on the second hard drive and they weren't viewable.

Error: "Windows Photo Viewer can't open this picture because you don't have the correct permissions to access the file location."

Filenames were green in explorer. So I tried using the backup of the encryption certificate and key. It seemed to restore just fine, but all the files were still encrypted. I tried the decript command "cipher /d" but that wanted to either be in the directory or specify the directory/filename and the list from the /u just flew by and would only scroll back so far.

After some more searching, found a .vbs script to find all the encrypted files... Read more

A:decrypt files files that I didn't encrypt

Well, from what I've been able to find and try, looks like those last two directories are simply not recoverable. Since I didn't encrypt them in the first place, I don't seem to have a key for it.

So, for the future...
What made it encrypt those directories so I can not do it again?
What should I do now to prevent problems like this again? Just backup my encryption key and try and remember where I backed it up to? The current one should be good for a while. One of the many things I tried was extending the expiration date to 2113.

If your computer ever becomes permanently unbootable and if you didn't back up your key with those files then Windows encrypted files will be lost. Beware of that. Accordingly people recommend True Crypt instead.

A:Don't want others see your files. Encrypt them with XP

Blade Jones makes a good point regarding NTFS encryption. It is a very valuable feature but you must understand the implications of using it. On this forum and others I have seen many cases where a user has reinstalled the OS or upgraded to a later version, only to find that important encrypted files are no longer accessible. This is a serious matter. NTFS encryption scrambles the contents of a file using a key that is a part of the user account. If that key is lost, and it will be when the OS is reinstalled., it is almost impossible to decrypt such files. Creating a new account with the same name and password will not create the same key.

It is possible to backup the encryption key before an OS reinstall but few people do so, or are even aware of the need.

With any encryption method involving a password be very sure you do not forget it! Forum rules do not permit help with lost passwords.

I believe it is becasue when you originally encrypted the file, it used the original user account information to create the hash, etc for the encryption. When yoou reinstalled, did you recreate the user accounts with the same names as originally created?

A:How do encrypt files on my windows 7?

Whether you need to protect internal or removable drives, BitLocker in Windows 7 makes that protection easy because it works with almost any drive. Windows 7 simplifies the encryption of internal drives by automatically creating the hidden boot partition
necessary to use BitLocker to protect the OS volume, eliminating the need to manually select that option during installation or to repartition the drive afterward. Best of all, BitLocker can be enabled on drives running Windows 7 with a simple right-click...STEP
1.To enable encryption you would right click a folder or file and then choose Properties from the displaying menu.
2.Once the Properties page appears you would click the Advanced button on the General Tab and choose the Select the Encrypt contents to secure data check box, and then click OK.
3.Another dialog box will come up to give you the option of applying the changes to the folder only or to the folder, any subfolders found and the files within.
[NOTES FROM THE FIELD] – It is important to note that once you start encrypting information that you should back up your encryption certificate which is the “key” to lock and unlock the data. If your certificate and
key are lost or damaged and you do not have a backup, in most cases where a local system is involved, that encrypted information is lost as it remains forever locked.
There are more recovery options available to you when ... Read more

I am attempting to encrypt files on a Windows 7 OS using EFS.
Receiving an error that states "The File Recovery certificate being outdated or expired is the most frequent cause of this invalid recovery certificate message".

I have located this to an expired certificate under RSoP, belonging to an account called sysadmin. The problem is that this laptop was a computer that I was given when I left my previous job. I'm presuming that account belong to the tech support team. It no longer exists under user accounts.
I've logged on with the Administrator account and recreated a certificate and generated the DRA, but still receive the same error. The certificate for sysadmin under RSoP still remains.

A:Unable to encrypt files using EFS

You're up a creek without a paddle man. EFS is non-trivial and you need the original Recovery Agent to access it.

Consider this scenario:

disk is EFS
user X has a password
user X account is deleted, but the data is kept
we discover, oops, we need something
recreate user X and even reuse the same original password
The encryption key is created such that it is unique to

the HD
the partition
the user
his/her password
time of day the password is created
The ONLY choice is to have created the Recovery Agent while the account was still active.

3) Is their any way we can make any file encrypted or if we need to how we can remove encryption of any file.


A:what are encrypted files ?? do we have any way to encrypt or decrypt and file ??

An encrypted file or folder is a file or folder that only someone with the appropriate permissions can view.

If you are the administrator of a computer with folders or files on it that you have created then you can encrypt them and only someone with the appropriate permissions i.e you and anyone else you give permission to can see and view the contents of that folder or file.

You can only do things with the file if you created it or are the administrator or have the appropriate permissions.

As a rule, I don't run NTFS on any of my systems and I advise against it in most situations. The reason is that I consider the additional stability and security that NTFS offers to be outweighed by the disadvantage of making it impossible, if not near impossible, to clean adware/spyware/viruses from an infected machine. But now I am presented with a new dilemma:

I have a laptop that I am using more as time progresses. It has a lot of information stored on it about my clients' user names, passwords, e-mail configurations, product keys (which they do lose, occasionally). Losing the laptop to a thief and the potential that the thief would discover the valuable and sensitive information stored on it . . . Well, I think you get the idea.

I am thinking of converting the laptop to NTFS and encrypting the many folders that contain sensitive information, thus protecting my clients from any potential damage due to loss of the laptop.

Here's the proposed scenario and conditions:
The laptop's hard disk is converted to NTFS.
Folders containing sensitive information are encrypted.
The OS on the laptop crashes and is unrecoverable.
I am forced to trash the existing OS and set up Windows 2000 or XP fresh and clean and start over again.
What must I do now to prepare for this day so that after the OS is loaded again, I can access those encrypted folders?

A:To encrypt (folders) or not to encrypt--that is my question.

How do I get back the files that were in an encrypted folder in Windows XP? I went to the User I used to encrypt them (right click on folder->encrypt folder and subfolders) and undid that option, but even though the folder and subfolders are no longer listed in green color (the color of encrypted folders) the files themselves are still gone, just the folders themselves remain, but no files at all that used to be visible in those folders. I hate encryption. I never thought it meant "hide these files from everyone, including ME." It's so stupid. How do I decrypt my folders, or, perhaps more accurately, how do I decrypt the files that used to be visible inside the folders and subfolders in the previously-encrypted folder?

Hi, My name is Janet and until Friday, 12 December 2014, I have never had a virus. I found this website while searching for help with Cryptowall after the thugs encrypted roughly my photos. I was doing a backup with three external hard drives from my laptop and everything is now encrypted - hundreds of thousands of photos. Sadly, I am desperate enough to pay the ransom, however, the links provided are all broken. I am wondering if anyone has received a working link from these thugs and if so would you provide it to me? The last 4 digits are what make us unique from each other - I would like to try a working link with my unique numbers to see if I can get through, pay with Bitcoin and get a key to my files. I spoke with the FBI office in Tampa, FL and they told me to just wipe my hard drive (?????) and not pay the ransom. If anyone can help me please contact me! I know everyone here understands how I feel. I am sick over this and in the middle of Christmas Card season with my clients, too! Thank you for reading and thanks for such a cool website and forum!!

A:Cryptowall Decryption Help?

Not sure if this will help but try downloading shadowexplorer and using it to view the files. I work at a computer repair shop and we have had 5 cases of cryptowall in the shop and this program allowed 1 customer to fully recover all of their files. It is not guaranteed to work so don't get your hopes too high (if you haven't already tried this, that is).also, if you have a non customer file that has been encrypted,try uploading it to decryptcryptolocker.com . I have not personally had any success with it, but hopefully you may. Also try downloading a copy of stellar phoenix photo recovery.it is a paid program but may allow you to recover the original (unencrypted) copies of the files that were deleted.just be sure to save them to an external drive to prevent corrupting any files that may be on the drive. Hope this helps.

I got caught with my pants down with a broken DFS/Backup policy and had to pay those bastards their ransom.  I received their decrypt utility along with the private and public key files.  The decryption works on some files but is causing corruption in JPEG files (or any file that uses JPEG internally; i.e. PDF, MPEG, Word documents) and larger XLS files.
I would like to try to decrypt them through alternate means since I have the key.  Using openssl rsautl -decrypt does not work because the files are large.
Any ideas?  We have a few crucial files that I'd love to be able to recovery.

First off, I consider myself a very savvy computer user. I have searched for a solution to this problem for a while, and I have an idea in mind, but it's a last resort. Here's my issue...

I ORIGINALLY had win 7 ultimate 32bit on my PC, with a total of 3 hard drives (one for OS, one for storage, and one for backup) I decided to encrypt them all with ultimate's bitlocker program. I didn't necessarily need the OS drive encrypted, but in order to "automatically unlock this drive", the system drive needed bitlocker as well... Not a big deal at the time I thought. Recently, I became enrolled in the MSDN Academic Alliance, where I had access to Windows 7 Pro 64 bit. Because I have the core 2 quad, with 4 gigs of RAM, I thought the 64 bit would run faster (as it would actually use all 4 gigs). So, I formatted my OS drive, and installed Win 7 pro 64 bit. So far, I love it. Except for one huge inconvenience... Everytime I restart my computer, my storage drive (where all my documents, etc. are stored), as well as my backup drive, are both locked. For those who don't know, Bitlocker is not included in Win 7 pro. HOWEVER, it does allow me to right click on the drive, and unlock it (password prompt). But because my OS drive is no longer encrypted (due to the fact that I formatted it, and can't put bitlocker on it with 7 pro), I no longer have the option to "automatically unlock these drives on this machine". I ALSO do not have the option to "turn off bitlocker&qu... Read more

Hi guys, I'm not totally sure this is the proper thread for this but I figured encryption might fall under security I thought I might give it a shot.

I play a game called Perplexcity, which has collectible cards, each featuring a mind bending puzzle. One of the unsolved cards hints that it needs to be decrypted using RC5. Right now there are hundreds of computers working together to solve the card but, as of yet, haven't. Looking it over and reading some things I think they might be going about it the wrong way, however, I have no tools to make my own attempts at it. The idea that the company would make people try to decrypt RC5.64 blindly is madness, so I think there is more going on than just that.

So, my question is this. I was looking around trying to find a program used in decrypting this but have come up empty. Can ANYONE point me in the right direction or, if you feel so inclined, upload the proper program to do this? I know it's out there as it's being used this minute, but I just feel like it's being used in the wrong way. Can anyone help?

Oh, and if you're curious as to what I'm talking about, check out this link:

Anyway, bottom line is, I'm looking for a name or program itself for cracking RC5 encryption. Any help would be GREATLY appreciated. Thanks!

A few months ago (April 2000), I ENCRYPTED a *.zip-file with the PGP-freeware (hope u heard of it). I wrote down my pass-phrase and de-installed the PGP-software a few weeks later, but let the file (xxx.zip.pgp) encrypted. Now I am in urgent need of this file I encrypted with the PGP software, but I CAN NOT DECRYPT IT with the current PGP software!!!! WHY?!?! I installed PGP-freeware 6.58, which is the latest one, and made EXACTLY the same passphrase like I did, to encrypt the data, but everytime I try to double-click the "xxx.zip.pgp"-file, PGP opens up a little window, telling me that my no pass sentence or something like that could be found! And when I click on the "unknown"-line in this window, the program tries to connect to a server, but everytime I get a "Server-error"! THIS SUCKS!
How do I DECRYPT a file which has been ENCRYPTED a few months ago, when another version of PGP was used?

we are in situation where
client is written in VC and server was written in Java.
we are using sun.rsa.crypto provider for asymetric Encryption(RSA). and clientside we are using Microsoft Base Provider.

the problem is , we are sending a certificate to Server from client , and server extracts public key from certificate and generates a string and encrypts with the extracted public key and sends it to client.
when client receives that encrypted string it need to decrypt with the corresponding private key .

can anybody tell me , how a decryption process can be done using RSA assymetric algorithm in VC with Microsoft Base Provider.

Thanks in Advance,

In the last week I have found out that part of my D-drive has
files where the attribute is set to encrypt, and I am
not able to take it off again by following the normal decryption logic of
clearing the check box and then OK and OK...
I tried restoring to an earlier date, it did not work

My D-drive consists of two folders: My Documents and Downloads
I figured out that I would want to back up My Documents regularly,
while I would need another folder for bigger files which I did not needed
to backup so often.
One of the things I like to keep is the installer file of a new program
I have downloaded, so that I can easily install the program again
either when it is corrupted, or when I move to another computer...

Now 95% of the files in Downloads are in green text,
I cannot access them, I cannot copy them to drive C or
send them as an attachment to the net, but I can move them to
My Documents, although they stay encrypted .

If I create another file inside the Download folder or copy a file from C to D
this new file is not automatically encrypted.

Can anybody please help, before I reformat my D-drive and
loose all the files I need?

The files are encrypted. The only way to unencrypt them is to log in with the exact account on the exact Windows installation that was used to encrypt the files. Unfortunately, there's no way around this.

Hello, I am trying to decrypt communication to SQL Server, which uses TDS.  The LOGIN packet is encrypted with TLS.  Specifically, here is the message I want decrypted:

I have added various certificates to the Options | Decryption list, but none of them do anything.  The Decryption tool window remains blank.  Is this because Message Analyzer does not support decrypting TLS within the TDS protocol?
Desperate, I tried to decrypt normal HTTPS (port 443) traffic using a browser to https://msdn.microsoft.com.  This at least filled the Decryption window with something.  But it was errors, "The cipher suite is not supported" and "Certificate
not found".  In addition to my self-signed cert, this also happened using a MS Authenticode cert I had issued to me, as well as the exported cert from the server I am communicating with over TDS.
These errors led me to believe I was using the wrong certificate.  Which certificate is required?  I have read Paul's blog and postings, and it isn't clear whether I can create my own self-signed certificate or do I need the "server certificate"
(certificate the server uses to TLS encrypt the data)?  The best I can gather is I can use a self-signed certificate when using Message Analyzer's "Unencrypted HTTPS" tracing (similar to Wireshark which uses Man-In-The-Middle).  But there
is another mode called Post Processing Decryption (or something simi... Read more

A:Decryption Certificates

I'm checking on the TDS/TLS support.  I can't recall if we've added that support yet, but if not we can add it to our list and try to resolve it moving forward.  For each different variation, we have to extend out support for TLS decryption. 
But we have certainly already increased the number of scenarios past RTM1.2 that we hope to make available soon.
As for the Certificate, you need the server side certificate.  The local client version of the certificate doesn't have the information required to decrypt the data.  So to decrypt MSDN traffic, you would have to go to the MSDN server and export
the certificate from there.  As for the cipher suites, this is decided by the servers configuration, and is exposed in the TLS negotiation when in the Server Hello packet.  Also the client has a local list that is supported, and the best one is chosen
based on the both lists.  You would have to limit or change the client or server side to find a cipher suite that is supported.

Okay here it goes, I'm running on one of my pc's is Windows XP Pro.....I had a folder with my study guides and resume in a folder called Certtraining...well one day I was playing around with EFS and encrypted the folder along with all it's subfolders on another physical volume say drive E. Well I d/loaded windows media player 11 beta and apparently caught a bad trojan since my system went from normal to super slow. I had my key for the encrypted file on my desktop in a folder and did not back it up to a disk..yeah I know duhhhhhh. Anyways I reformated the C drive since I was unable to repair the bug/trojan/virus (I was running bitdefender but still didn't catch it.ummm??) Well when I had my system back up and running and tried to open the encrypted file I was denied access to my files. I dont have the key to open this file so I'm out of luck unless I place it on a fat drive which I did on the same machine but still was unable to open the folders. Is there another way (Im guessing if I place it on a different machine say windows 98 maybe I can open it...any ideas or is there any tools out there that can decrypt this folder...I need my study guides badddd. Thnks in advance.

I encrypted a Folder with important *.doc and *.odt files on a external Harddrive. Now I can't decrypt them . Now I get "Access to *.dot was denied". I installed SP3 on the computer without turning on the external harddrive. And thats when it may have happened, but I removed it again and it still does not work.

Can anybody tell me what my options are? Any tweaks, settings, references to other tolls, or may be even the 1-800-Manufacturer? Or would you know where to go and get help for this. And if ownership can't be verified where and how can we/I do that?

Any suggestions are greatly needed and appreciated.

I have a HP Pavilion Media Center Edition 2005 SP2. My problem is I cannot open encrypted files after a reinstall of the OS. But I have learned from past mistakes and I have a backup of C: drive on my external L: drive. After trying to fumble my way through this new territory of encryption/decryption I am no further along than when I first started. I am hoping, this time, I have all my ducks in a row to recover from this. Can someone help me through the steps to reinstall public keys, certificates, and recovery agent that I used to encrypt these files or is this possible. Thanks.

Hi folks, long time lurker here.
OK, last year, a good mate of mine fell foul to ONE of the ransomware scams. **every** precious photo he owned was scrambled. Yes, no back up!!!!
This was before just cryptolocker and he seems to recall the old FBI / Metro police / Scotland yard porn warnings.
He couldn't shift it and formatted the HD but of course, after his files had been encrypted. I suspect the decryption key was stored on his PC.
So, he asked me if I could help as I have a bit experience with things like this. And his missus is pi55ed as the wedding / holiday / kids etc pics are now all unreadable.
I have discovered ALL the encrypted files start with : CR_M0x04ì7     8  when viewed with notepad.
We also now have some encrypted files from his PC and the identical NONE encrypted files which are on my computer as I gave them him those files back in 2004!! Obviously the metadata is different but the pics are identical.
I have just tried the Panda decryption util (pandaunransom) and it generated a key but doesn't seem to decrypt them.
Can anyone here offer up a bit of a suggestion I could try. He's a good mate and I do feel for him. I would be gutted to loose all my pics. Hence 3 backups at my site.
Pics are only small, happy to upload if anyone wants to try...
Thanks for any suggestions.

Hi cornz CryptoLocker was the first malware that actually encrypted the files and asked for a ransom. And it was spread way more than a year ago, last June. So I don't think that your friend was actually hit by it, but maybe by another Cryptoware. Are the file extensions the same (.pdf, .png, .jpg), etc. or are they different?Here's the FAQ on CryptoLocker:http://www.bleepingcomputer.com/virus-removal/cryptolocker-ransomware-informationIf you want to make sure that it wasn't CryptoLocker, you could try uploading one of the encrypted file on DecryptCryptolocker.com, by FireEye and FoxIT and see if a private key matching the encrypting is found.
