— Use this option to find the newest viruses
Scan for new unknown viruses
that might not have existing "cures." This option uses advanced heuristic
techniques that try to match files to the signatures of known viruses, while
also looking for telltale signs of unidentified viruses in the files.
This scanning method also looks for file traits that can generally rule out
that the file contains a virus. This minimizes the chances that Scan gives a
false indication. Nevertheless, if a heuristic scan detects a virus, you should
treat it with the same caution that you would treat a file that you know
contains a virus.
This option provides the most thorough scan, but is generally slower than
a normal scan.
