Avast PC scaning.

Hi.
I have some question about Avast scaning.
I start use Avast after Window Defender and Avira ( I use Window Defender before Avira)
Does Avast ignore what other Anti Virus has done and scan everything anyway ?

(I may have allowed some threat with Window Defender and make some stupid action with Avira)

With exception to Windows defender, which should be automatically disabled by Windows when you install another 3rd party resident/on-access antivirus.

Other previous antiviruses should be completely uninstalled to avoid possible conflict.

Avast isn’t going to know what other antiviruses have scanned it doesn’t have access or know what it may or may not have scanned and the actions you took.
