postheadericon Windows does not start bsod user32.dll missing after avg virus removal


windows does not start. Windows gives a BSOD while booting saying “ user32.dll missing “


NB: You should only do this if you understand what you are about to do here

There are several solutions to this problem:

  1. For windows vista

    Insert your vista CD and boot from it and let it repair your installation.

  2. For windows XP

    insert your XP cd and boot from it, using the R option to repair your installation we can now enter the text “ copy c:\windows\system32\dllcache\user32.dll c:\windows\system32\ “

    If there is no dllcache with user32.dll in it use the cd, go to the dir x(cddrive):\i386\ and type " expand user32.dl_ c:\windows\system32\ “

  3. The last option is to use a live boot cd to preform a system restore, after this boot in safe mode and remove AVG without cleaning out the virus vault.

  4. For more references look on the AVG support site


If you are using AVG they did a wrong update making user32.dll come up as a valid virus.

When you choose to remove this file your pc won't be able to boot anymore. And you will have to replace it with a new copy.

Sir: My Free AVG Anti-Virus 8.0 has evidently
been expired by you because I can't turn it on
anymore rendering it useless & I cannot get into my Outlook Express or my Internet Explorer.
I tried to remove your program from "Add or Remove Programs" in my Computer and it fails.
Will you kindly remove it from my Computer completely or send me an E-Mail tellin me how I
can remove it completely.
Thank You, Frank Natale, E-Mail:
