So a new version of what has always been the most reliable program on my computer has been released. Great? No. Avast 7 after even a cursory glance at this forum should still be in beta, in short V7 IS NOT WORKING PROPERLY (sorry for shouting). I have had video files (legal in case anyone was wondering) cast into the ether because v7 decided, mid muxing that the process was suspicious. Webrep in 6 was a decent reference tool but in 7 sits in my browser inert, the three bars constantly blank and when I click said bars a blank utterly useless rectangle pops up. Avast two days after the update decide that it couldn't start, forcing me to safe mode and the removal tool. The scanning process, while quicker than v6 found "No Threat" while a scan by Malwarebytes uncovered a trojan, and don't even get me started about the sandbox.
In this new version it seems that Avast is trying a new way of working, all good, in the fast moving world of threat detection to stay still is to move backward. The only problem is that in the normal run of things a program is tested exhaustively in beta BEFORE being foist on the general user, and "tested exhaustively" is a term that in no measure could be applied to Avast7. That testing is happening now, The general user is being forced to deal with issues that 90% have not got the know how to deal with. I have for some years now recommended Avast to anyone and everyone as the best free AV out there, but with this new version, until they sort things out, my only recommendation will be: Don't update to V7.
