Well, good to see that there are reports of this issue on the forums. I called up avast tech support yesterday and the person I talked to said my call was the first they’ve heard of the issue. It took me a little while to get the message thru though. At first the person I was talking to thought chkdsk was a third party program and wanted me to create an exception in the firewall and/or refer to the avast user manual. Once I got the message through that chkdsk (I was referring to it as disk check) was a built in Windows tool and that it was running during the boot up process, when nothing else should be using the hard drive, the person was like “Yeah, that’s odd. Try uninstalling and reinstalling the Free version.” They resent my license file for IS, so I went ahead and uninstalled avast completely and reran chkdsk in boot up. It ran fine without issue. Then installed avast free and did the same, except chkdsk reported that a software package was in the way and it couldn’t run.

I plan on calling them again later to let them know that it’s still a problem, and to also point out that it’s been reported on the forums. If avast tech support and/or the devs don’t look at these forums, they really should.
