back here with a link to one you say does work. There have been quite a number of pop-up scanning ads offering to check your PC for free and they never come back with a clean report. Next, they want your money to fix things that aren't broken. In some cases they plant nagware and worse on your PC. When you see these pop-up ads, don't click anywhere on them. Even the "X" to close the program is often bogus. The best way I've found to shut these down is to close the browser.
