Hey, I recently downloaded a dodgy torrent as i was looking for software to get files back which had been permanently deleted by mistake.The program was called 'Recover my files' When i installed the software it all looked real and started bringing up my files which had been deleted and then all of a sudden my screen just went off but the cursor was still there. i rebooted my pc and it continued to happen so i pressed F8 at startup and clicked on last good known configuration, this brought my screen back and everything seemed to be normal again. I uninstalled the program which had caused this and ran a virus check using mcafee and no threats were found, however when i boot up my pc the start menu keeps reloading itself as if it's doing it for the first time like when you first load up. This happens every 10 seconds or so. Everytime i try and go into something which is part of windows e.g my documents, my computer it will bring it up but then when it reloads itself, it will close these off making it impossible to do anything. It still works ok to go on the net and browse as i am doing here and also msn messenger sometimes loads up and i can use other programs. I've tried doing a system restore as this seemed like the logical thing to do and this seemed to stay open but i've only had my pc back a week and i've not got any restore dates so far.
Sorry should have mentioned that i am running XP
Hope you can help

Many Thanks

Dan

Hi Dan_GHTM,

Before we begin...
Can you set a system restore point? This will give us something to fall back on in case of a glitch. Let's begin with a MalwareBytes Scan.

Please download Malwarebytes Anti-Malware and save it to your desktop.
alternate download link 1
alternate download link 2
  • Make sure you are connected to the Internet.
  • Double-click on mbam-setup.exe to install the application.
  • When the installation begins, follow the prompts and do not make any changes to default settings.
  • When installation has finished, make sure you leave both of these checked:
    • Update Malwarebytes' Anti-Malware
    • Launch Malwarebytes' Anti-Malware
  • Then click Finish.
MBAM will automatically start and you will be asked to update the program before performing a scan.
  • If an update is found, the program will automatically update itself.
  • Press the OK button to close that box and continue.
  • If you encounter any problems while downloading the updates, manually download them from here and just double-click on mbam-rules.exe to install.
On the Scanner tab:
  • Make sure the "Perform Quick Scan" option is selected.
  • Then click on the Scan button.
  • If asked to select the drives to scan, leave all the drives selected and click on the Start Scan button.
  • The scan will begin and "Scan in progress" will show at the top. It may take some time to complete so please be patient.
  • When the scan is finished, a message box will say "The scan completed successfully. Click 'Show Results' to display all objects found".
  • Click OK to close the message box and continue with the removal process.
Back at the main Scanner screen:
  • Click on the Show Results button to see a list of any malware that was found.
  • Make sure that everything is checked, and click Remove Selected.
  • When removal is completed, a log report will open in Notepad.
  • The log is automatically saved and can be viewed by clicking the Logs tab in MBAM.
  • Copy and paste the contents of that report in your next reply and exit MBAM.
Note:
-- If MBAM encounters a file that is difficult to remove, you may be asked to reboot your computer so it can proceed with the disinfection process. Regardless if prompted to restart the computer or not, please do so immediately. Failure to reboot normally (not into safe mode) will prevent MBAM from removing all the malware.

-- MBAM may make changes to your registry as part of its disinfection routine. If you're using other security programs that detect registry changes (like Spybot's Teatimer), they may interfere with the fix or alert you after scanning with MBAM. Please disable such programs until disinfection is complete or permit them to allow the changes.

Hi Dan,

We have a problem

IMPORTANT NOTE: One or more of the identified infections (C:\WINDOWS\system32\drivers\tdssserv.sys (Trojan.Agent)) was related to a rootkit component. Rootkits and backdoor Trojan are very dangerous because they use advanced techniques (backdoors) as a means of accessing a computer system that bypasses security mechanisms and steal sensitive information which they send back to the hacker. Many rootkits can hook into the Windows 32-bit kernel, and patch several APIs to hide new registry keys and files they install. Remote attackers use backdoor Trojans and rootkits as part of an exploit to gain unauthorized access to a computer and take control of it without your knowledge.

If your computer was used for online banking, has credit card information or other sensitive data on it, all passwords should be changed immediately to include those used for banking, email, eBay, paypal and online forums. You should consider them to be compromised. They should be changed by using a different computer and not the infected one. If not, an attacker may get the new passwords and transaction information. Banking and credit card institutions should be notified of the possible security breach. Because your computer was compromised please read How Do I Handle Possible Identify Theft, Internet Fraud and CC Fraud?

Although the rootkit was identified and removed, your PC has likely been compromised and there is no way to be sure the computer can ever be trusted again. It is dangerous and incorrect to assume that because the rootkit has been removed the computer is now secure. In some instances an infection may have caused so much damage to your system that it cannot be completely cleaned or repaired. The malware may leave so many remnants behind that security tools cannot find them. Many experts in the security community believe that once infected with this type of malware, the best course of action is to wipe the drive clean, reformat and reinstall the OS. Please read:

"When should I re-format? How should I reinstall?"
"Help: I Got Hacked. Now What Do I Do?"
"Where to draw the line? When to recommend a format and reinstall?"

Should you decide not to follow that advice, we will do our best to help clean the computer of any infections but we cannot guarantee it to be trustworthy or that the removal will be successful. Let me know how you wish to proceed.

Hi rigel, I'm going to need a little time to think about this. After i thought the pc was working again i plugged in my external hard drive to transfer some folders over. The hard drive contains drivers, photos and music. I hadn't plugged it in since downloading the virus as i thought this might infect it but now that i've done it, could the external hard drive be compromised as well? I don't have too much of a problem reformatting if this would be ok but i'm guessing that the files on there could also too now be infected. If this is the case then i think i would like to try and remove the remaining files. I understand the consequences of this. I don't do online banking. I occasionally shop online. I have changed the passwords using a different computer. I will have a think about it first and get back to you.

Again many thanks

Anytime an access is made, there is always a chance. Did you move any files to the external drive? I would unplug it for now to keep it isolated.

A few words...

If you reformat, things start fresh. Some people swear by that every couple of years anyway.
If you opt to clean, everything may turn out fine as well. What we will do is run a final program and then refer you to the HJT forum so those techs can use more powerful tools.

After everything is clean, then you can scan the external to make sure everything is safe.

If you have any questions, please ask.

I'm going to opt for a complete rebuild. It seems the more logical solution. I did transfer some music last night and some pictures that i permanently deleted but my friend said he would scan the external hard drive before transferring anything across but i'll keep it seperate until pc has been formatted. Thanks

That sounds good. There are pros and cons for both approaches. Good luck, and if we can help with anything, let us know.
