Change the scope of what files are checked.
This setting affects not only file-related checks
but also the scheduled virus checks. What to Check:
All Files checks every file. This
is the most thorough, but most
time consuming check. Use this
setting if you use non-standard
file extensions for your program
or document files.
Program Files checks all
program files, such as .Exe,
.Com, .Dll file types. This will
miss macro viruses, which are
found in certain document
types.
Document Files checks all data
files recognized on your PC.
This will miss program-related
viruses.
Program and Document Files
checks both program and data
files. This is the default setting
and the second most thorough
check. It will miss only
virus-infected files that have
been renamed using a
nonstandard program or
document type.
