Yes, it's true! I don't recommend it. The viruses are nasty too, they will make you think your computer is no longer good at all and that you need to buy a new one. It will make your DVD disappear, your copier won't be there, I even lost my ram in the process. Aside from all this, if they catch you downloading something illegal, they will fine you thousands of dollars, for something you could have bought for 99ct. It will also slow down your computer. No, it won't crash with McAfee, but McAfee may not detect some of the worms or trojans until it's too late.
IT Administrator, see this stuff all day long.
