Avast 6.0.1367 on XP suddenly slow

rrf494g

I ran full scan of Avast Version 6.0.1367 with virus defns 120201-0 today for the first time and after 3 hours only 3 percent complete. It usually takes less than 3 hours to to the whole thing! Have used avast for years with no trouble - I ran process explorer along side, for a while, to ensure no malware etc and, sure enough, avast was taking 100% ish of cpu utilisation.

Anybody else had a sudden massive increase after an update to this version?

been investigating SLOOOOW Avast further. Now on Virus defns: 120201-1, but still on 6.0.1367 program version.

Speed when scanning C: drive (with usual mix of file types) = 80 MB per sec BUT speed when scanning mp3 music files = 1.1 MB per sec; also, when normal scanning, speed is limited by disc access speed but when scanning mp3 files, disc access is infrequent and speed is limited by CPU availability.

Can't now use Avast for "full scans". What has happened to Avast scanning mp3's ? Any clues ?

PROBLEM NOW FIXED

After another version of Avast released, the speed to scan mp3 folders increased from 1.1 MB per sec to 170 MB per sec. Avast back to being useable, after briefly being useless.
