Resolution

Question/Topic:

When configuring detection settings, each of the VirusScan Enterprise scanners allows you to fine-tune the list of file types scanned.

Using wildcards
When using wildcards, these limitations apply:

Valid wildcards are question mark (?) for excluding single characters and asterisk (*) for excluding multiple characters.

Wildcards can appear in front of a backslash () in a path. For example:
C:ABC*XYZ matches C:ABCDEFXYZ.

An exclusion containing question mark (?) characters applies if the number of characters matches the length of the file or folder name. For example:
The exclusion W?? excludes WWW, but does not exclude WW or WWWW.

The syntax is extended to include a double asterisk (**), which means zero or more of any characters including backslash. This allows multiple-depth exclusions.
For example: C:ABC**XYZ matches C:ABCDEFXYZ and C:ABCDEFDEFXYZ, etc.

Resolution/Workaround:

Specify files, folders, and drives to exclude from scanning operations. You can also remove any exclusions you specified previously.

1. From the VirusScan Console, open the scanner's property pages, then select the Detection tab.
2. Click Exclusions.
