Title: windows screwed after boot scan
Post by: cenobytez on July 25, 2007, 10:38:33 AM

Installed latest version of avast on windows xp home machine, found a couple of trojans, needed to schedule a boot time scan. Ran this, selected option of move to chest, took out a couple of windows files (including winlogon.exe) - now pc will not boot at any level, get the following error message:-
STOP:C000021a (fatal system error) The windows logon process terminated unexpectedly with a status of 0xC0000034 (0x00000000 x 0x00000000) the system has been shutdown.
how can i retrieve the files from the chest or get into windows to get the files back

Just perform a repair install.

Overinstallation can solve the problem and you won't lose your programs, settings, data, files, etc.
Just choose 'Repair' installation of Windows and install 'over' the old installation.
