I installed a trial version of one of their products and found out that they had also installed one other piece of software which invaded all three of my browsers, changed my settings in them, signed me out, and installed yet another extension on two of the browsers. The registry needed to be cleaned separately and, to be honest, I'm not sure, after an hour, that I've gotten everything off my computer. I can't speak to their software but, in my opinion, any company that pulls stunts like this don't need my trade.
