I know this issue has been posted for months and months by other users and I have been patiently waiting for a program update to fix this but the latest program version that I installed (Avast Internet Security ver. 2015.10.0.2208) did not fix it and this is really really getting old. After a scheduled full scan, Avast says Threat Detected" but the show results button shows nothing. Then checking the log and checking the scan history shows that there are 0 detections/infections. First of all, my wife keeps panicking when she sees "Threat Detected". Secondly, today I realized that the Avast has become useless to me after the last couple scans when I didn't even check the scan history to make sure this was a program glitch because I am so used to Avast being wrong. Then I realized that if this had indeed been a real infection I wouldn't even have known because I am so used to Avast incorrectly telling me there is a threat when there is not one, that I just ignored it.
I am seriously considering changing Antivirus programs because of the glitch.
Will this ever be fixed?
