• Scan compressed files. Select the Compressed files checkbox to
have the module look for viruses in compressed files or in file
archives. This option ensures that viruses do not spread from
compressed files, but because the module uncompresses these files
before it scans them, choosing this option can lengthen the time it
takes to scan a given set of files as you work with your computer.
Š NOTE: When the E-Mail Scan module examines a file archive,
it will scan only the file archive itself, not the compressed files
within the archive.

contain no executable code, whether script, macro, or binary code.
You can, therefore, safely narrow the scope of your scan sessions so
that the module examines only those files most susceptible to virus
infection.To do so, select the Program files only button.
