MasterTip: Before you even think of turning on your PC turn on your brain. Clicking on one iffy message less or don't download and run an obscure exe is better than to have to scrub your PC. By the way. After I've done some(not realy much) research this site seems to be legit but the exe you can download doesn't realy say anything what it realy does. At least Avira didn't bark after I scaned it. So for me this download looks quiet suspisious in my humble opinion and I would never execute this thing.
The government should sponsor websites like this, and make them more thorough. Less savvy internet users can learn something and protect themselves better, and less computer problems in society == less chaos in life.
