Antivirus applications

Some antivirus applications may reduce the performance of Avamar backup operations. Most antivirus applications scan a file for viruses when you open the file. If the antivirus application scans each file during a backup, then the disk and backup program performance is slow.

To reduce backup times and prevent the antivirus application from scanning each file as Avamar backs it up, add the avtar.exe file to the exclusion or safe list for the antivirus application. The settings and steps to do this depend on the antivirus application. For example, McAfee refers to these exceptions as low-risk processes.
