Avast Service Consumes 100% of the CPU. SOLUTION?

100% CPU Avast Service.

Avast is one of the best free antivirus you can put on Windows , in fact I use it myself on my work PC. However, like many similar programs, it can also be very demanding in terms of resources. That is why in some circumstances it is possible that we will see that the Avast Service process consumes 100% of the Windows CPU, which could become a problem. But don’t worry, howpchub will give you some tips that can solve this problem in a simple way.

Why Avast Antivirus Consumes Many Resources?

Antivirus and other Malware programs often consume large amounts of resources as they often perform operations such as:

  • Comprehensive system scan for viruses .
  • Cleaning.
  • Background analysis .
  • Background updates.

All of these can lead to situations where Avast services slow down your PC . So if your computer’s CPU is at 100%, you can follow this tutorial or the instructions in this video to find out if this antivirus has anything to do with this high consumption 👇.

Restart your PC

It may seem like something very simple, but you can’t imagine the number of problems that are solved with a simple restart. That is why the first piece of advice I give you if avastsvc.exe consumes a lot of CPU is to restart your computer .

In the event that after the restart the CPU continues at 100% with Avast Service , I advise you to go to the next tip.
