Was your avast on automatic update and was it updating once or twice a day?
Is the virus allowing you to update it now?
The Norton may have been messing up your avast, you can’t have two antivirus programs at one.
Norton was. How do you get old pre installer Norton off a machine? Uninstall? I tried once on a laptop and it is freaking hard.
Trying Malware Bytes is safe mode now. This thing really sucks.
