If I can just “amplify” a little on Technical’s comments …
False-positives, especially if you get quite a few of them, usually relate more to the defs than to the program itself. There’s been a few (rare) times in the past when an update to avast defs generated an unusual number of FP’s, which of course resulted in a flood of users’ reports here (and probably direct to the Alwil team too). And each case, a new set of defs was issed quite quickly which eliminated most if not all of those new FP’s.
