How to fix the problem where MsMpEng.exe uses up a lot of CPU.

If you are facing issues like “MsMpEng.exe high cpu usage”, then it might be due to some malicious program that is causing problems with your computer. To solve this issue, we recommend downloading Malwarebytes Free Antimalware and run a full scan on your device. This tool will help you identify and delete all types of threats including adware, spyware, viruses, trojans, worms, rootkits etc.

Step 1: Look for Malware on your computer.

Malware infections are one of the most common causes of computer crashes. They can slow down computers, make it difficult to use certain programs, and even freeze up the entire operating system. While there are several different types of malware, we’ll focus on viruses here. A virus is a type of software that replicates itself without permission and spreads to other files, folders, and drives. Once infected, you might see popups asking you to pay money to fix the problem. Or you could lose data.

If you suspect your computer is infected with a virus, you should immediately download a free anti-virus program. There are many options out there, including Microsoft Security Essentials, Avira AntiVir Personal Edition, Panda Cloud Antivirus, AVG Internet Security, Bitdefender Free, Kaspersky Total Security, Norton 360, and ESET Smart Security. We recommend downloading each of these programs and running a full scan. If you don’t know how to do this, check out our guide on How to Scan Your Computer for Viruses.

Once you’ve scanned your PC, you should delete anything suspicious you find. This includes temporary files, cookies, browser history, cache, downloaded files, and hidden items. Then, reboot your computer.

You should also check your router settings to ensure that your firewall isn’t blocking incoming connections. And finally, try unplugging your modem and router for 30 minutes to see if that helps.
