I'm on XP service pack 2.

A few Hours ago I ran into some problems with my USB connection, SO I uninstalled the port from the device manager and had add hardware do an auto-detect and then rebooted. (don't think this is the problem, maybe a symptom though.)

After my reboot I didn't have a task bar, internet explorer won't run. I did a ctrl alt del to get the run prompt and tried doign explorer.exe, didn't get my task bar up though. So I tried to go to a stystem restore... no valid system restore please restart.

So I started firefox to see If I could go online that way... and I could. But my homepage and searchbar had been hijacked. So I decided this sounds alot like a virus. Tried to run Livecare... not a valid 32 bit application. Tried running my older copy of avguard... disabled. Tried to download... Malwarefix? not important, the important part is that It won't install because I'm missing valid windows installer now. I tried to install windows installer from microsoft... not a valid 32 bit application. (Oh, Did the previous in both normal and safe mode.) Finally, I Then decided to try backing files up onto a dvd... and learned that I can't copy or move files period.

I Know that an amature like myself shouldn't try and fix these problems on his own, So I haven't taken any steps beyond these to try and fix the problem. (I Do know my way around a pc, and am more than willing to take them with some guidance though.)

Summary: I Gots me a virus, no task bar, can't install many microsoft/ anti-virus programs, including windos installer. I also can't modify files beyond deleting them... no copy no move.

*Edit: Oh, I disconnected my pc from my network, and am using a backup pc to post

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. Reagardless 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.

Some types of malware will disable MBAM and other security tools. If MBAM will not install, try renaming it. Right-click on the mbam-setup.exe file and change the .exe extension to .bat, .com, .pif, or .scr and then double-click to run.

If after installation, MBAM will not run, open the Malwarebytes' Anti-Malware folder in Program Files, right-click on mbam.exe and change the .exe as noted above. Then double-click on it to run.
