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 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?.
