Antivirus treats different software differently.
Antivirus scans zip files differently to other files.
Please try the suggestion. It wasn't made just to fob you off or waste your time. It was made because it may actually solve things, and has solved things for a lot of other people recently.
If it doesn't work, please make a Process Monitor log of what happens, and we'll investigate that.
But if we see antivirus active in that log then we aren't going to help any further because there's no point in us suggesting solutions if you decide they can't possibly be true without even trying them.
