Whether I run a scan either in regular or thorough mode, I choose to exclude certain folders on my "C" drive from the scan, so I uncheck certain folders, when I setup the scan. However, I notice that Avant seems to scan them anyways. Can I exclude certain folders in Avast Free or is this only possible in Avast Professional? If I can exclude them, please tell me what I am doing wrong, then how to correct it. As a non techie, please make your reply easy to follow. Thanks.
