Title: Specialized definitions for the boot-time scan can't be installed
Post by: _Iceman_ on August 26, 2021, 10:28:30 PM

Hi all, there's a problem with specialized definitions for the boot-time scan, I click "install" and after a few seconds it says they are successfully installed. But then if I reopen the same window it says the definitions aren't installed and I need to install them again. Repair didn't help. What could be the problem?

And by the way, what's the difference between specialized definitions for the boot-time scan and virus definitions?

Hi,

Can you add a screenshot of the message saying "definitions aren't installed", please?
When you click Install definitions on the Boot-Time Scan screen, Avast Antivirus downloads all virus definitions from a cloud database. If you skip installing specialized definitions, Boot-Time Scan scans your PC based only on the last virus definitions that were downloaded.

I click "Install definitions", a green bar runs forwards and backwards and after a few seconds it says "Specialized boot-time scan definitions installed". But if I click "Back" and then reopen the same boot-time scan window it again says "Install definitions" (screenshot 1).

So even if virus definitions are up to date (screenshot 2) do I still need to install specialized definitions if I want to run a boot-time scan?
