Fûřqąń,

keyloggers are always (at least) suspicious, there is nothing to fix for avast since they are detected correctly.

I don’t know what other files you have submitted, but it can very well be that they are detected correctly too and that there is nothing to fix.

and what if person don't have Internet access (Like most of my friends don't have internet access ) then this antivirus is useless to them . because if Definition not got updated then you will always get that Suspicious warning every-time and you won't be able to install that Clean / Legit Software
They can always go to a place with internet (school, library, neighbors, cyber café etc) and download the latest updates and install them at home.
What if suspicious files are 10,20
Well, why not stop using suspicious software.
