In this article, we will explain why antivirus runs in the background and is there a way to stop Avast from running on startup? If you End the Task process this anti-malware tool will run when you restarted your PC. The problem starts from here when you turned off Avast completely you will still find AvastSvc.exe running in the task manager. It uses very little ram and disk usage but gives you high scanning speed and detects malware instantly.īut if you are somehow dealing with Avast service high CPU problem then you may want to stop Avast completely from running at startup or in the background. You can also play around with configuration settings in order to try to figure out what software and feature causes certain types of disk activity.Why would you want to stop Avast from running in the background? When it’s the best anti-malware tool for Windows PC. What directories/files are being accessed? There will probably be at least some activity you don't understand, but try to mentally or actually filter that out and zero in on the activity in question. Look at what is performing filesystem operations and what those operations are. Depending on what you have running (in the background), more frequent and heavy disk activity might be normal (at times).



So especially if my network connection is disabled and nothing can be updating in the background, unusual/heavy disk activity stands out and is easy to spot via Procmon. I typically disable background and scheduled tasks such as malware scans, backups, disk defragmenting, search indexing, etc and minimize the processes/services started up and running in the idle state.

Did you say what OS you are using? Yes, Process Monitor would be a tool you could use to investigate filesystem activity (and other types of activity if those aren't disabled.
