Thank you so much Ron, that did it! BUT: When I tried to update within Malwarebytes, it happened again! So I was forced to revert once again to the manual rules you provided. Should I wait until the automatic update rules file changes, perhaps the current one has some issues with my particular setup? Weird since I have two PC's, and it's only happening in one, and also, it's happening in the healthiest one... Also, strangest thing: right clicking to analize with Malwarebytes does not work anymore... Thanks for your help and patience, I'm new to MBAM, it worked fine for a couple of days until this started to happen.
