Aye there are loads of those fake products that make it seem like you got virusses and they 'they" can remove it. then you download it, bit to remove it you need to pay. While infact they only install virusses and other malicious software. I suggest you fully follow the guide, just to be sure, but if you don't have any messages that you have virusses on your computer (from the fake program!), you should be safe.
