Description
When anti-virus software is not configured to limit the amount of time spent trying to scan a file, the total effectiveness of the anti-virus software, and performance on the system being scanned, will be degraded. By limiting the amount of time the anti-virus software uses when scanning a file, the scan will be able to complete in a timely manner.
