During the last month or two I've both heard and experienced that Avast! is blocking totally safe programs. It may even prevent downloading them. In my list there's at least one commercial Finnish bookkeeping program, Passeli. Cubase by Steinberg Software is another one, the using of which requires a dongle. Anyone ever heard about a virus requiring a dongle??? Both will install fine, but pretty soon the .exe of both of them will end up in quarantine. Today I learned, that Avast! prevents downloading the game AcesHigh by HiTech Creations. What makes these hard to pinpoint is that all three I mentioned have been around for years, over a decade or even several! The AcesHigh download prevention was even more puzzling, since I could download almost everything else from their Downloads, most of that being .exe files! I believe that's the problem with the ones who reported today that they can't run Battlefield 4 or SkyDemon.
I've found a workaround: If a download is restricted by Avast!, dropping the shields temporarily will help. For safe and legitimate programs getting quarantined, the cure is to put them on the Exclusions list.
Although the above mentioned tricks work, I believe it would be best for business to fix this issue as soon as possible.
