When i open Downloads folder, avast freezes computer. I was scanning PC with Malwarebytes and HitmanPro and they did not find anything.In the settings, I have set up the heuristic to high. Other settings are deafult. I’m using avast! Free Antivirus 7.0.1474. Is it a bug? I tested other antivirus programs and there’s no problems. Sorry for bad English. Thanks
With three scanners all running together I’m not in the slightest bit surprised. Less so when you also have avast set to high heuristic sensitivity.
I personally wouldn’t use hitmanpro as there have been some adverse reports from some malware removal specialists that it has deleted important files.
When running a scan by a 3rd party scanner, as it opens a file to scan it, this is likely to trigger avast to lock the file and scan it first. You are complicating this even further by having multiple 3rd party scanners running scans so there is a great deal more activity by avast as these open files to scan.
