I’m using avast! v4.8 Pro with the latest updates/definition files. In doing a scan, a cab file was detected as having a text file infected with PC-Flu II. I extracted the files to investigate but was not given an alert and everything looks fine viewing it with a hex editor. Two odd things: 1) I only get the warning when I scan the directory containing this file, not when scanning the file itself and 2) I move it to the chest, I scan it inside and it shows clean, but it’s infected again when I restore it and rescan. Lastly, I thought maybe it was something else setting off the alert in the cab file, but it is this text file.
Any ideas what could be causing it to set off??
