Yes it would be useful to identify the unscanned files. The reason is this, Yesterday I got a virus which was not found by Avast but a notification from Safari said a virus downloaded. I closed the MacBook down and restarted it. Closed off airport and ran a full scan.
The Avast scan found the Trojan virus as ‘cedrick 'nitch' collomb PDF’ infected file - nothing I downloaded deliberately.
Now the previous scan the day before was clear but had 12 unscanned files now after the infection and even though Avast removed and deleted the Trojan virus I now have 13 unscanned files which seems very odd to me and so I would like to check what it is or what are the13 unscanned files . So how do we do this?
Cedrick 'Nitch' Collomb is the name of the author of
https://en.wikipedia.org/wiki/Unlocker , a Windows program that contains no malware.
So you downloaded a PDF with his name, but what would be interesting to know, malwarewise, would be the name of the trojan, not the filename.
If you want to see what items weren't scanned just right click on the report window list and select 'Non-scanned'. There are no settings that govern what the logs show or not, just use the right-click menu.
