If it is indeed a false positive, or because of what they say some AVs detect it and you are happy to accept their word and the possible risk, add it to the exclusions lists (Standard Shield, Customize, Advanced and Program Settings, Exclusions) and periodically check it (scan it in the chest), there should still be a copy in the chest even though you restored it to the original location. When it is no longer detected then you can also remove it from the Standard Shield and Program Settings, exclusions.
Also see (Mini Sticky) False Positives, how to report it to avast! and what to do to exclude them until the problem is corrected.
Whaoo !!!
yesterday i had sign of trojan-gen on the executable,
and today it’s okay, avast didn’t detect the program as virus again,
(and it is not, trust me, you can see sources, it’s a GPL program)
really quick answer to my problem.
thanks to the team
