Avast false positive?

I've been using Avast for about a week now -- I previously had AVG but switched because of apparent compatibility problems with MS Office.

Anyway, Avast has today started giving me notice that it's detected a "Rootkit: hidden file", C:\WINDOWS\system32\drivers\sfloppy.sys. I suggests the appropriate action is to delete it, so I click okay. I then allowed it to reboot my PC and do a boot-time scan, as it suggested. That resulted in four notifications of corrupted files, but no trojans or anything nasty.

Then, a bit later the notice about the same file popped up, and I clicked on OK again to delete it again. But using Windows Explorer I see that the file is still there -- and the Avast notice has just popped up yet again.

The file size shows as 11.1KB whereas info on the internet http://www.file.net/process/sfloppy.sys.html suggests it should be 11,392 or 10,496 bytes. Seems like Avast can't delete it, so should I do so manually -- or maybe just move it to another location for a while to see if my PC really needs it?

I would go to the Avast Forum and see what is in there regarding it.

I know when I first started using Avast I got 3 false positives in the one go which nearly knackered my computer.

P.s just choose to ignore it to save the popup from recurring!

Thanks guys. The warning hasn't popped up yet in this evening's session, so maybe Avast has forgotten about it already ;-)

I started to receive the same warning after the latest update today, and after downloading a new version yesterday evening. So it appears that there is something wrong on Avast's side. If so let's hope that they make the necessary corrections?.
