It started with annoying pop-ups, and error messages saying my computer has several fatal errors. After which I was directed to rogue anti-virus software pages. I did a full scan with my Norton antivirus and fixed the problems listed. My computer started running slow, junk advertisements were still popping up and I could not access certain webpages. So I rebooted my computer and at start-up, an error message came up: windows failed to initialize userinit.exe properly (Oxc0000005). Click on OK to terminate the application. This happened twice. After clicking ok, the desktop loads with no icons nor taskbar. Pressing ctrl-alt-del came up with another error: This feature has been disabled by the administrator. Wanted to try system restore, however, I could not go further than one day, which was when I started getting those pop-ups!
Things I have tried (in safe mode):
Spybot Search & Destroy (Free version)
FixVundo (from Symantec)
After running Malwarebytes’ Anti-Malware, I was able to start windows in normal mode (with icons and all). But the system was very slow. So I ran it again and it was still picking up threats. I then followed the instructions found here: http://ezinearticles.com/?Remove-Vundo-and...&id=1255229
The final VundoFix scan step did not pick up any threats. So I restart my com in normal mode. Again, I got a blank screen (my desktop background was initially set to none). This time, ctrl-alt-del worked. However, I could not run explorer. Under the processed tab, there are many applications running, including explorer. I ended explorer and went to file -> run, type in explorer and the start button came up. After quite some time, there was an error message: Windows cannot find “(null)”. Make sure you typed the name correctly, and then try again. To search for a file, click the Start button, and then click Search.
Restart in safe mode again and ran Norton antivirus. It picked up Trojan.Vundo with the action stating: partially resolved. It also picked up W32.IRCBot and was stated as fully resolved. Tried FixVundo after that and it could not detect any Vundo Trojan in the scan. Restart in normal mode and the same thing happened ("null" error).
Can anyone help me? What else can be wrong with my computer?
