The bees knees, the cat's meow, hot damn! What ever your age this one is good. When ever you are surfing on the Internet and a popup appears saying that your computer is infected and you can click here to get a free scan...DON'T!
That is the infection and if you do click on it you are giving that site permission to download and run a file on your computer. Not good.
