I got the same pop up window/locked computer issue others have had along with a loud beeping sound. I called the number, they "fixed it" after two tries and many, many hours. I paid them a service fee of $180 but then they tried to sell me all kinds of service plans and additional software packages and just won't go away and leave me alone. I'm going to take my laptop to a local computer repair shop and make sure they haven't left anything behind that gives them the ability to re-infect me. I truly think they infected my computer on purpose.
