The FTC has caught on to two companies selling useless products to technical illiterate people using tactics that "trick the consumer into thinking their PC is infected." The companies still have their original sites running... making huge promises that include one piece of software to "speed up your machine by '216 percent.'"

It is sad to think that people out there fall for tricks caused by companies such as these. I ,personally, know people that would go for something like this and potentially open their computers to dangerous malware and even pay for the product.
Make sure you do research into the company, outside of their own site, to make sure that it isn't a scam. Being on the LTT forums I expect most here already know how to be safe on the web but I will reiterate the importance anyways... if something is to good to be true, it probably is.
