Key notes
MRT.exe, also known as theMalicious Software Removal Tool, is a program that Microsoft adds to protect your computer from malware. It’s a pretty handy tool but has the issue of usinga lot of CPU resources.
Normally, this isn’t really a problem because MRT only runs every once in a while. The problem lies when MRT begins to run for an extended period of time; even days on end. Now, something’s wrong.
What causes MRT.exe to malfunction and use a lot of the CPU?
Besides high CPU usage, other notable symptoms include your computer becoming really hot and scanning errors. To understand why this happens, it’s important to look at the likely culprits.
How can I stop MRT.exe from using CPU resources?
In order to stop the Malicious Software Removal Tool from malfunctioning, you need to first figure out what’s wrong with it. You can do this by checking the software’s logs.
Before you delve into your computer’s files, there are a couple of quick solutions we recommend you try out:
1. Check MRT logs
If it says no infection was found, there’s nothing else you can do. The problem lies elsewhere. If it does say something was found, proceed to the next solution.
2. Delete and reinstall MRT.exe.
3. Use Autoruns to clear up errors
