Avast is not allowing the windows start menu to open. Each time I want to access a program, I must repair avast and/or restart my computer. I have explored tje fix for this and everywhere it states that it is an avast problem. Is there something I should change in my settings or exclusions or can you fix this? Can't go back to Windows 8 now so only choice is to choose another anti virus program unless you can help. Thanks!
