I was browsing the Help file and found out that F-Prot does have a special scan settings where you can specify the scan mode/level - quick, normal (default), and Thorough. Found in Advanced/Advanced Scan setting. I am trying to find out whether the Normal and Thorough modes differ in their Heuristic settings. It seems like the main difference is the scanning of archives. Normal mode will only scan level 1 in archive whereas the Thorough mode will scan deeper inside the archives?
