I understand that AntiVir PE is excellent and thorough with archives when running a system scan. However, it would seem that the Guard for real-time scanning of archives is quite limited. I was testing it with Thunderbird to see how well it reacts to viruses in the mailbox in real-time with the EICAR sample in a 7z archive and a 7z SFX archive. - It did not alert me when receiving the messages with those attachments - It did not alert me when saving those attachments to the hard drive - It did not alert me when viewing the archive contents in 7-Zip The only time it alerted me was when I extracted the archives. This leads me to believe that AntiVir PE does not scan MIME types (Thunderbird Inbox file) or archives real-time. The option to scan archives in the Guard settings is checked but must relate only to files compressed with run-time packers, but I thought that might have included the 7z SFX archive. This is good in a way because now I know AntiVir PE will not destroy my Thunderbird Inbox if a virus was found. But I thought that it would have at least scanned the archives when saving to the hard drive, that is not so good.
