My computer was infected with 2 viruses in 2 days. I was able to delete them (I think) using Malwarebytes' Anti-Malware but now my system goes to the Blue Screen almost every time it's on, after a few hours. The latest error stated: "A driver has corrupted the memory management system PTES" and "Stop 0X000000DB" I had also received a different Stop (0X0000007B).
I don't know how to get rid of whatever is affecting/infecting my system. We use Windows XP. Also, when I use MSN's Bing to search, and click on a link, I am being redirected to a weird site that begins with Clckr.

Can anyone help shed some light on this issue? I ran Malwarebytes again a few minutes ago, but later got the blue screen. Thank you!

Our next step:

Before we start fixing anything you should print out these instructions or copy them to a NotePad file so they will be accessible. Some steps will require you to disconnect from the Internet or use Safe Mode and you will not have access to this page.

Please download Dr.Web CureIt and save it to your desktop. DO NOT perform a scan yet.
alternate download link
Note: The file will be randomly named (i.e. 5mkuvc4z.exe).

Reboot your computer in "Safe Mode" using the F8 method. To do this, restart your computer and after hearing your computer beep once during startup (but before the Windows icon appears) press the F8 key repeatedly. A menu will appear with several options. Use the arrow keys to navigate and select the option to run Windows in "Safe Mode".

Scan with Dr.Web CureIt as follows:
  • Double-click on the randomly named file to open the program and click Start. (There is no need to update if you just downloaded the most current version
  • Read the Virus check by DrWeb scanner prompt and click Ok where asked to Start scan now? Allow the setup.exe to load if asked by any of your security programs.
  • The Express scan will automatically begin.
    (This is a short scan of files currently running in memory, boot sectors, and targeted folders).
  • If prompted to dowload the Full version Free Trial, ignore and click the X to close the window.
  • If an infected object is found, you will be prompted to move anything that cannot be cured. Click Yes to All. (This will move any detected files to the C:\Documents and Settings\userprofile\DoctorWeb\Quarantine folder if they can't be cured)
  • After the Express Scan is finished, put a check next to Complete scan to scan all local disks and removable media.
  • In the top menu, click Settings > Change settings, and uncheck "Heuristic analysis" under the "Scanning" tab, then click Apply, Ok.
  • Back at the main window, click the green arrow "Start Scanning" button on the right under the Dr.Web logo.
  • Please be patient as this scan could take a long time to complete.
  • When the scan has finished, a message will be displayed at the bottom indicating if any viruses were found.
  • Click Select All, then choose Cure > Move incurable.
  • In the top menu, click file and choose save report list.
  • Save the DrWeb.csv report to your desktop.
  • Exit Dr.Web Cureit when done.
  • Important! Reboot your computer because it could be possible that files in use will be moved/deleted during reboot.
  • After reboot, post the contents of the log from Dr.Web in your next reply. (You can use Notepad to open the DrWeb.cvs report)

Thank you--when I attempt to restart in Safe Mode, it goes to the Blue Screen again, with this message:
A problem has been detected and windows has been shut down to prevent damage to your computer.......
Check for viruses on your computer. Remove any newly installed hard drives or hard drive controllers. Check your hard drive to make sure it is properly configured and terminated.
Run CHKDSK /F to check for hard drive corruption, and then restart your computer.


I am not able to leave this blue screen without turning the computer completely off. Is there a remedy for this, so I can follow the instructions for running Dr. Cure It? I did download & save it to my desktop without running it.

Here is the log from Dr. Web:

skynetvcvnsgml.sys;c:\windows\system32\drivers;BackDoor.Tdss.262;Deleted.;
CouponPrinter.ocx;C:\WINDOWS;Adware.Coupons.34;Incurable.Moved.;
exe[1].exe;C:\WINDOWS\system32\config\systemprofile\Local Settings\Temporary Internet Files\Content.IE5\95S7IABV;Trojan.Fakealert.4742;Deleted.;
SKYNETvcvnsgml.sys;C:\WINDOWS\system32\drivers;BackDoor.Tdss.262;Deleted.;


Once I rebooted, the blue screen came back, with a STOP: 0x0000008E message. I had to turn it off manually, so I hope the viruses were able to be removed.

Please advise when you get a chance. I appreciate the help!

You have a rootkit infection - TDSS variant. This is a nasty infection. I recommend changing all on-line passwords from a known clean computer. If you are using a wireless router, please make sure you have a password on the admin account.

Please download Sophos Anti-rootkit & save it to your desktop.
alternate download link
Note: If using the vendor's download site you will be asked to register with MySophos so an email containing an activation link can be sent to your email address.

Be sure to print out and read the Sophos Anti-Rookit User Manual and Release Notes.
  • Double-click sar_15_sfx.exe to begin the installation, read the license agreement and click Accept.
  • Allow the default location of C:\Program Files\Sophos\Sophos Anti-Rootkit and click Install.
  • A message will appear "Sophos Anti-Rootkit was successfully installed. Click 'yes' to start it now". Click Yes.
  • Make sure the following are checked:
    • Running processes
    • Windows Registry
    • Local Hard Drives
  • Click Start scan.
  • Sophos Anti-Rootkit will scan the selected areas and display any suspicious files in the upper panel.
  • When the scan is complete, a pop-up screen will appear with "Rootkit Scan Results". Click OK to continue.
  • Click on the suspicious file to display more information about it in the lower panel which also includes whether the item is recommended for removal.
    • Files tagged as Removable: No are not marked for removal and cannot be removed.
    • Files tagged as Removable: Yes (clean up recommended) are marked for removal by default.
    • Files tagged as Removable: Yes (but clean up not recommended) are not marked for removal because Sophos did not recognize them. These files will require further investigation.
  • Select only items recommended for removal, then click "Clean up checked items". You will be asked to confirm, click Yes.
  • A pop up window will appear advising the cleanup will finish when you restart your computer. Click Restart Now.
  • After reboot, a dialog box displays the files you selected for removal and the action taken.
  • Click Empty list and then click Continue to re-scan your computer a second time to ensure everything was cleaned.
  • When done, go to Start > Run and type or copy/paste: %temp%\sarscan.log
  • This should open the log from the rootkit scan. Please post this log in your next reply. If you have a problem, you can find sarscan.log in C:\Documents and Settings\\Local Settings\Temp\.
Before performing an ARK scan it is recommended to do the following to ensure more accurate results and avoid common issues that may cause false detections.
  • Disconnect from the Internet or physically unplug you Internet cable connection.
  • Clean out your temporary files.
  • Close all open programs, scheduling/updating tasks and background processes that might activate during the scan including the screensaver.
  • Temporarily disable your anti-virus and real-time anti-spyware protection.
  • After starting the scan, do not use the computer until the scan has completed.
  • When finished, re-enable your anti-virus/anti-malware (or reboot) and then you can reconnect to the Internet.

Sophos doesn't recommend removing things it doesn't recognize.

Please rerun Sophos ARK and delete the following files:
  • Hidden: file C:\WINDOWS\system32\SKYNETctjtsdxc.dll
  • Hidden: file C:\WINDOWS\system32\SKYNETbnvelame.dat
  • Hidden: file C:\WINDOWS\system32\drivers\SKYNETvcvnsgml.sys
  • Hidden: file C:\WINDOWS\system32\SKYNETnwgdoapn.dat
  • Hidden: file C:\WINDOWS\system32\SKYNETxjwyojni.dll


Reboot your computer immediately

Upon restart, please update and rerun Malwarebytes - post the new log.

The scan completed successfully, however, when I reboot and pull up the log, it still states that the files will be cleaned upon restart. I'm afraid to empty the dialogue box out of fear that the system has not deleted the hidden files.

Is there a definite way to ensure the files were cleaned? I have rebooted several times and the message is still the same.

I appreciate all of your help!
