Avast giving me problems?

Seems like Avast is giving me problems? I’m having some computer freezing, browser, avast, file explorer. Avast would not run from Safe Mode. I see avast is doing something way to often?

How many times a day is avast updating virus definitions?

How do I stop avast from scanning my files for non malware reasons?

How do I know what it is working on so often?

Getting ready to switch to another av if I can’t get answers!

It might help if you asked specific questions and gave us some actual information.
