RE : error message during Avast update

During Avast update ( auto or manual … have tried both !! ) I recieve the message " Avast caused an error in Avast will now close " . This message appears after download and almost complete install of update files . I recently had to format my hard drive and re-install windows ME due to possibly … guess what , a virus >:( ( I know !! but this was before I installed Avast ) . Any ideas ?? ???

What version of avast are you using, 4.8.1229 is the latest (you say you have the latest but didn’t confirm the version) ?

What other security software do you have installed ?

Try a repair of avast. Add Remove programs, select ‘avast! Anti-Virus,’ click the Change/Remove button and scroll down to Repair, click next and follow.
If that doesn’t work try, uninstall, reboot, install, reboot.

One of my friends had an similar problem, and an repair of avast! fixed it.

Do you have any other antivirus installed?
Is your computer clean? Can you check with one of the on-line scanners?
Kaspersky (very good detection rates)
ESET NOD32
Trendmicro housecall
F-Secure
BitDefender (free removal of the malware)
