Hello, I first had issues with avast using too much CPU now but I fixed it. Now I have problems with it slowing down openings of ZIP files. I downloaded Eclipse SDK and when I tried to open it in WinRAR, it took 5 minutes to open. When I disabled avast, it opened in seconds. My PC CAN handle avast. It has an AMD FX 8 Core, 8 GB of Corsair RAM, and a WD Black. My settings in avast File shield are: All packers, High sensitivity, Use code emulation and test for PUPs.
