Every month or so avast blocks a program that I know to be non-malicious. The message even says avast doesn't have enough information about it to declare it malware, but it still blocks the program AND terminates it after an onscreen countdown, without giving me any options. (It does this for more than one program; none of the programs are from giants like, say, Microsoft or Adobe, but they're not from unknown fly-by-nights either.)
After terminating I'm asked whether to open the program "next time" in the sandbox or normally, but I have to choose "normally" twice (that is, run it and let avast terminate it again) before that choice sticks. Then it all happens again in another month or so.
This is very annoying. How can I tell avast to PERMANENTLY trust certain programs? Or failing that, is there a way to halt and cancel avast's (rather useless) countdown to termination. I feel this design is far too intrusive and simplistic, and I actually switched to avast because it was billed as being smarter than other AV programs in this respect.
