File Filter

On this page you can manage options of Dr.Web ICAPD on the protected server (Internet gateway) for checking files and data downloaded from the Internet:

•In Block files part, specify types of the received unsafe objects that must be blocked by Dr.Web ICAPD.

▫Infected—scanned file contains a known virus

▫Suspicious—scanned file marked as suspicious

▫Adware—scanned file contains an adware

▫Dialers—scanned file contains a dialer

▫Jokes—scanned file contains a joke program

▫Riskware—scanned file contains a riskware

▫Hacktools—scanned file contains a hacktool

▫Unchecked files—the file cannot be scanned.

•Use heuristic analysis—instructs Dr.Web ICAPD to use the heuristic analysis on the protected station to detect unknown threats. Note that heuristic analysis may slow down the file system monitoring but improves its reliability.

•Scanning time of one element—restrictions on maximal time spent on scanning of one file by Dr.Web ICAPD on the Internet gateway. If the value is 0, scan time is not limited.

•In the Maximum nesting level part, you can specify settings which Dr.Web ICAPD is used for checking compound files (containers) of the following types: archives, mail files (email messages, mailboxes), packed objects and other containers (i.e. compound files that are not classified as archives, mail files or packed objects).

For each of the types you can specify in the corresponding field the maximum nesting level. The objects that are nested into container deeper than the specified level are skipped during scanning the container by Dr.Web ICAPD. For example, if you want scan the contents of the archives which are nested into archives, specify the maximum nesting level not less than 2. To disable scanning of nested objects, specify 0 as the maximum nesting level for the corresponding type of containers.

Note that increasing of maximum nesting level slows down the file checking.

The Maximum compression ratio field allows you to specify maximum compression ratio (as a ratio of size of compressed file to its original) for compressed files. If compression ratio of a file is greater than the maximum allowed, the file is skipped during the check.
