Fake System Optimization Tools Use Fear to Scam Consumers

After a few years, any computer can feel a bit sluggish. So when a website claims it has found disk errors that are slowing your PC, it's no wonder many users will jump at the chance to try and speed up their machines with an optimization tool like SystemDefragmenter or DiskDoctor. According to web security firm CyberDefender, these tools, and many others like them, are nothing but fakes that try to scare users into paying for a full version from an unsecure website.
