If my memory serves me right, you used to be able to set a default action in previous versions of avast. My default would be to do nothing, I would just check the aswBoot.txt report of the boot-time scan and see what if anything it found.
I have just done a couple of boot-time scans but I didn’t set any actions.
But after some investigation I found it is still possible to set actions. When you go to AvastUI > Protection > Antivirus > Other scans - Boot-time scan, click on the cog (icon) settings and check the ‘Automatically apply actions during scan (check this box to select an action)’ option.
This expands the window to allow to input actions for Virus, PUP or Suspicious detections. I left these at the No Action. This should allow it to complete the scan, but you would have to check the Scan History or the aswBoot.txt report in the C:\ProgramData\AVAST Software\Avast\report folder.
