Exclusions

Top  Previous  Next

In the Exclusions section, you can specify the list of files and folders to exclude from the anti-virus check.

To edit lists of files and  paths excluded from scan

1.In the Excluded paths and files line, specify a path to corresponding file or folder.

2.To add a new line, click , and specify a path in the new line.

3.To remove a path from the list, click next to the corresponding line.

The list of paths excluded from the scan can contain the following elements:

1.Direct path in the explicit form to the excluded object. And:

A character \ or / excludes the entire disc with the Windows OS installation folder,

A character \ at the end of a path excludes the folder from checking,

A path without a character \ at the end—all subfolders of the selected folder are excluded from checking,

For example: C:\Windows—skip scanning files of the C:\Windows folder and all its subfolders.

2.Masks of objects, excluded from the scan. The ? and the * symbols can be used to specify masks.

For example: C:\Windows\*\*.dll—skip scanning all files with the dll extension at all subfolders of the C:\Windows folder.

3.Regular expression. Paths can be specified through regular expressions. Any file those full name (with the path) corresponds to a regular expression is excluded from checking.

Before starting Dr.Web Scanner for Windows familiarize yourself with recommendations on virus scanning for computers operated by Windows Server 2003 OS, Windows 2000, or Windows XP OS. The information can be found at http://support.microsoft.com/kb/822158/en. The article is meant to help you increase system performance.

The syntax of regular expressions used for excluding paths from scanning is as follows:

qr{expression}flags

As a flag mostly the character i is used. It instructs "to ignore letter case difference".
