System Mechanic, IOLO, is nothing more than a scam to infect your computer and continue to take your money. Do not let them convince you of their "money back gaurantee".

The Guarantee is false! You will never see your money again once you have allowed them access to your credit card.

Their "experts" are in India and have no idea what they are doing. I spent at least 16 hours on the phone with them. They only made my situation worse.

No promised refund ever appeared!

Stick with Norton or Symantec. These are really the only legitinate protectors.

Don't learn the hard way like I had to.
