This feature allows you to exclude application processes from Antivirus On-access scanning only. These exclusions help minimize the risk of potential conflicts and improve the performance of excluded applications which in turn has a positive effect on the overall performance of the operating system. The exclusion of a process / application is, in fact, an exclusion of its executable file (.exe).
You can add executable file into the list of excluded processes via Advanced setup (F5) > Antivirus > Processes exclusions or using the list of running processes from the main menu Tools > Running processes.
This feature was designed mainly for the purpose of excluding backup tools. Excluding the backup tool's process from scanning not only ensures system stability, but it also does not affect backup performance because the backup is not slowed down while it is running.
Click Edit to open the Processes exclusions management window where you can Add exclusions and browse for executable file (for example Backup-tool.exe) which will be excluded from scanning. As soon as the .exe file is added to the exclusions, activity of this process is not monitored by ESET Mail Security and no scanning is run on any file operations performed by this process.
You can also Edit existing processes or Remove them from exclusions.
