So, been using the program for years. Went to use it today and the program had been completely removed from my computer (Verified this in the Control Panel). I did not manually remove it. So I went to download it from the PatchMyPC website and the site was flagged by Norton Antivirus as a dangerous website and refused to let me in, stating in the message "Threat Category: URL:Blacklist".
False Positive. Apparently, Norton will not allow the user (you) to over-ride and deletes the file. This is true of other AVs, too. Try to find one that allows you to over0ride. Malwarebytes will allow over-rides and several others will too. Check AV reviews and find something else.
