When this feature is enabled, the scanner analyzes the likelihood that it is a variant of a known virus. Select any combination of these options:
- Find unknown program viruses. This option is selected by default. Treat executable files that have code resembling a virus as if they were infected. The scanner applies the action you choose on the Actions tab.
- Find unknown macro viruses. This option is selected by default. Treat embedded macros that have code resembling a virus as if they were infected. The scanner applies the action you choose on the Actions tab to those files.

- Under Non-viruses, specify whether you want the scanner to find non-virus programs that are potentially unwanted.
- Find potentially unwanted programs. Detect programs that are potentially unwanted.
- Under Compressed files, specify which types of compressed files you want the scanner to examine. You have these options:
- Scan inside packed executables. This option is selected by default. Examine compressed files that contain executable files. A packed executable is a file that, when run, extracts itself into memory only. Packed executable files are never extracted to disk.
- Scan inside archives. This option is selected by default. Examine archive files and their contents. An archive file is a compressed file that must be extracted prior to accessing the files within it. Files contained inside archives are scanned when they are written to disk.
- Decode MIME encoded files. This option is selected by default. Detect Multipurpose Internet Mail Extensions (mime) encoded files, decode them, then scan them.

NOTE
This option is not the same as Also scan for macro viruses in all files on the Detection tab, which instructs the scanner to find all known macro viruses. This option instructs the scanner to assess the probability that an unknown macro is a virus.
When you select this option, the E-mail Scan Warning dialog box appears.
WARNING
VirusScan Enterprise does not take any action on potentially unwanted program files or joke programs that it detects. Detections are logged in the log file.
If you want to take action on a detected potentially unwanted program file or joke program, you must take action manually. For example, if you want to remove a detected joke program, you must remove it manually.
NOTE
Although it does give you better protection, scanning compressed files can increase the amount of time required to perform a scanning activity.
