Just installed new version after lots of experience with old version on XP x32. I am now running Win 7 x64. Returnil reports one of my files known to be good (Teracopy.exe) as a problem. When I try to add it to the exclusion list I find that I can not. I browse to the file and press the "open" button only to be told that I don't have permission to open the file. I am the admin on that machine. First of all, why do I want to "open" the file instead of selecting the file to add to the list? Secondly, I don't want another antivirus at all but I don't see a way to not run the av. How can I add the file to the list?
