Option
Description
Scan all files
Scan all files regardless of the filename extension. If you turn on
this option, the other options on the Extensions
tab are turned off.
Scanning all files will affect computer
performance, so we recommend that you only turn on this option as
part of a weekly scheduled scan.
Scan only executable and other vulnerable
files
Check all files with executable file extensions (for example,
.exe, .bat, .pif) or files that have the possibility of being
infected (for example, .doc, .chm, .pdf).
Quickly check the structure of all files, and then scan them if
their format is that of an executable file.
Additional file type extensions to be
scanned
To scan additional file types, click Add, and then type a file
extension such as PDF in the
Extension box. You can use the wildcard ? to
match any single character.
To stop scanning a file type, select its
extension in the list, and then click Remove.
To change a file type, select its extension in the list, and
then click Edit.
Scan files with no extension
Files with no extension could be malware, so we recommend that you leave this option
turned on.
Exclude
To exclude specific file types from on-access scanning, click
Add, and then type a file extension such as
PDF in the Extension
box.
To start scanning a file type, select its extension in the
list, and then click Remove.
To change
a file type, select its extension in the list, and then click
Rename.
