Figure 18. Selecting the file types scanned for viruses
Tip:
Do not forget that someone could send a virus to your computer with an exten-
sion (e.g. .txt) that is actually an executable file renamed as a .txt file. If you
select
Scan programs and documents (by extension)
, the scan would
skip such a file. If
Scan programs and documents (by content)
is se-
lected, the extension is ignored, and analysis of the file headers will uncover
that the file is an .exe file. File Anti-Virus would thoroughly scan the file for vi-
ruses.
In the
Productivity
section, you can specify that only new files and those that
have been modified since the previous scan should be scanned for viruses. This
mode noticeably reduces scan time and increases the program‟s performance

Compound Files
section, specify which compound files to scan for virus-
