I would suggest that you try a repair of avast. Add Remove programs, avast! Anti-Virus, Change/Remove button and scroll down to Repair, click next and follow. You need to be on-line to do this.
This may or may not work, but it won’t do any harm.
Just an update, I am guessing it is in Avast now for sure. I use Copernic Desktop Search. I just started it to find my copy of Yahoo IM so I could try reinstalling that, but got the same error.
Also did a “Repair” of Avast in Add/Remove programs, but still get the error.
Also, only seem to get the error when I am connected to the internet. (As far as Copernic Desktop Search goes.)
When I disconnected from the Ineternet (only on dial up No High speed wher I am at.) The desktop search program did not report the error. Reconnected to the net and then the error started again.
Waiting for a new Hard drive to get here next week then I am going to do a new system build and will be reinstalling everything.
New AMD 64 3000+ and MSI K8Nero4 mother board and 250 gig SATA drive. So Might just wait until then and see what happens with the clean install.
Can the string “dep_fsSetFileAttributes” be found in your version of the file aswCmnOS.dll? (without the quotation marks)
Does avast work normally (i.e. do you have the avast icon in the tray, for example?)
