Hi All...
As far as I can determine, this problem still seems to exist for Boot Scans. The log does show up in the hidden Avast file folder as mentioned in posts above, but there are no log results shown in Scan History through the Avast interface. I, and many others, are seeing this on W7, W8 And 10 machines. The Boot Scans did show up under Scan History in all prior Avast versions, but is not longer showing in current versions. There is one person who posted a screenshot to this thread showing Boot Scan results under Scan History in German (the only screen shot of this that I have ever seen). Perhaps there is some program difference between the German language version and other versions, or the user has some setting activated that many of us are not aware of.
I am hoping that someone from Avast will take notice and address this and resolve the issue.
Thanks very much...
