I have a computer that when booted in NORMAL mode would only boot to a black screen with the mouse curser. I rebooted into safe mode and all icons and task bar loaded. I RAN msconfig to see what was running. Braviax and antivirus pro 2010 were listed. The internet will not work in regular or safe mode. I downloaded malwarebytes, spybot, and superantivirus on another computer, put them on a memory stick and put it in the infected computer. None of the programs would run without changing the SETUP file name. After I finally get the programs installed, I had to also change the name of the executable file to get the programs to run. Each program would run for about 5 seconds and then the window would close. When i tried to reopen the file I was told I didn't have permission to open the file. I looked online how to remode tdss. Everything that I could find about showing hidden devices, no tdss listed. I looked in windows\system and windows\system32 and no tdss files FOUND. I did a search for tdss and it found nothing. Then explorer.exe stopped loading EVEN in safe mode. I had to reboot and then in normal and safe mode I was getting BSOD when I clicked on the user name to load. Then I logged in as admin and ran SDFix. That got rid of the BSOD but explorer.exe still doesn't load. I ran combofix. Explorer.exe still doesn't work and internet still doesn't work in normal or safe mode. THe computer will now let me run malwarebytes and spybot. I ran both and malwarebytes found 0 infections and spybot found 1 infection for vurtuomond. I have Avira Antivir rescue cd and the only thing it is finding is SDFix. Does anyone have any idea how I can get the computer clean and operating normal? Any help would be greatly appreciated.
