No doubt us that a reasons for the success of the solution from Microsoft is a very content consumption of resources, an aspect that is still important for most veteran teams. Below we offer some simple tricks to further optimize its operation without losing one iota of security:

Opens MSE, configuration, change the date and time by default for analysis by other know that you will have the computer on (e.g. at lunchtime or before starting work).

Without leaving tab configuration, it limits the CPU usage value to a maximum of 10%. The analysis will take a little more to complete but you can continue using your usual applications without losing so much performance.

You can access the Windows Task Manager and locate process msseces.exe. By clicking with the right button you can assign a lower priority, leaving more resources for the rest of your system uses. We recommend to try it, and if you notice one improves evident, use programs such as Prio to make the change permanently (by default only applies for that session).

Disables the sending of reports with MAPS marking the option do not wish to join MAPS. In certain scenarios it may cause application crashes or a running slower than expected when it is not possible to send the report.

It excludes some locations to accelerate the analysis, such as additional hard drives for backups or folders where you store multimedia content. It is important that you assume that those directories will not be scanned or will be protected with the detection engine in real time.

Occasionally some applications can create conflicts with the antivirus. Check the configuration of your P2P software and, of course, never install more than one antivirus on the same computer.
