Have a look at the screenshot below these words.
My PC is all infected with those nasty viruses. I had no idea that my browsing was so unsafe and that I was such a poor computer user. Oh, that’s right, I run Linux and I don’t have a C:/ or D:/ drive or any viruses. As a Linux user, I don’t even have to worry about adware removal. This is a genuine public service announcement: after Christmas, lots of you will be returning your PCs and laptops to the store because they run slowly or not at all. A number of you will have had these problems after clicking one of those free virus scan ads. They are a scam and will put viruses onto your hard drive. So, a plea: for the sanity of the poor techs and salesmen who gave you a perfectly good machine either browse sensibly or install Linux (even better, do both) and you’ll never have to worry about this sort of nonsense again.
