Rootkit scan do not work in avast screensaver!

How to run this scan in on-demand, on-scan & scr?

also, I can scan BIOS & CPU by avast?

It is done automatically 8 minutes after boot.

It is also done as a part of the on-demand scan when you choose the Standard or Thorough sensitivity for the scan.

I don’t believe any AV scans the CPU and more than likelt the same for the BIOS.

If you use the Professional version of avast! you can do a Rootkit scan manually.
There you can choose between a fast and a thorough Rootkit-scan…
