[SOLVED] After upgrading Avast error c000021a
« on: February 27, 2011, 10:42:21 AM »
After upgrading Avast I reboot and the PC crash at logon with error
STOP: c000021a (Fatal System Error). The Windows Logon
Process System process terminated unexpectedly with a
status of 0xc00000080 (0x0000000 0x00000000). The system
has been shut down
I can't go also in safe mode (a similar error) wath can I do ?
Maybe Avast installed some driver in the last release ?

yours

Are you using XP, if so do a search on the code
Seems to be a known problem and not dependent on your AV

Yes I use XP,
but I did a search, the rare people that received this error
(complete with 0xc00000080) seems to solve with a reistallation,
I think it depend from the AV because the error appeared at reboot after
upgrading the AV, and I saw that the upgrading downloaded a SYS file.
I don't do anything else in this session.

Or repair
From the look of the Microsoft KB's on the subject it isn't so rare
Have you search Technet

What version of XP are you running, especially the SP
XP dosn't back up all of the hives, so whilst it shouldn't make things worse....

he should try boot into safe mode / safe mode with networking and uninstall Avast there then

and ofcourse upload the dumps if any present

(i dont think renaming the avast asw*.sys files to e.g. asw*.sys_disabled in Windows XP will work w/o issue)

Use a live CD and copy the file to another medium
It may help, but....

thanks for replay but in recovery console the last working configuration don't
do anything, I already try it

another thing is the asw*.sys the only file loaded by the registry ?

I think I am losing it :-[
I do not understand the quoted above
If you cannot get access to Windows - no logon, no safe mode etc how can you 'see' what is loaded by registry
