It’s obvious more an anti-virus problem than a game problem. Most of the people install anti-virus programs but don’t know how to customize it to work the way they want. That’s a false positive, but as per default most anti-virus programs immediately deletes to quarantine any suspicious file. First you must disable that automation by requesting you to confirm any deletion before it happens. When that happens either you confirm the deletion of the file, or if you know that it is a false positive, you can create an exception for that file, so when the anti-virus scans it again, it knows not to put the file into quarantine and ignore it. Look for info on false positives, or exceptions at the McAfee website or through Google.
