After the login screen shows the welcome screen, my computer does not load my desktop or anything. . . just a plain blue screen. When I try to start explorer manually via task manager, it says that it cannot find it and to make sure I typed it correctly. I can access everything just fine in safe mode but not in normal. When I open the command prompt it says the directory is c:\windows\system32 instead of c:\users\home (home is my user name). I think there may be a virus or something that is preventing explorer from starting in normal mode. If anyone can offer any suggestions, any help is greatly appreciated. Thanks in advance.

There's no error message with the blue screen?
Can you get into Safemode?
Reboot the computer and after the initial screen shows, start tapping the F8 key. If "Boot to last know good configuration". try that or Safemode w/networking

Yes, I can boot into safe mode with no problems but the last known good configuration does not help. There is not an error message like with the BSOD, this is just a plain blue screen. I have no taskbar, no icons and when I open the task manager, the necessary startup processes have no description listed - unlike in safe mode or when I was able to log in normally. When I try to open explorer manually I get this message. . . "Windows cannot find 'c:\windows\explorer.exe'. Make sure you typed the name correctly, and then try again". Hope this helps.

We can try a couple of scans in safemode to see if there's an infedtion present. Do you have an original Windows Vista CD?
------------------------------------------
The process of cleaning your computer may require temporarily disabliling some security programs. If you are using SpyBot Search and Destroy, please refer to Note 2 at the bottom of this page.

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.

Note 2:
-- 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. To disable these programs, please view this topic: How To Temporarily Disable Your Anti-virus, Firewall And Anti-malware Programs

---------------------------------

If mbam won't install

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 on it 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.

If Garmanma's help doesn't do it, then restart into safe mode -- go to the run command and type MSCONFIG hit enter-- go to the startup tab and uncheck everything in there. Now re-start in normal mode, if your computer starts normally then you have a driver that isn't cooperating properly.
