Trojans, Viruses, and Worms

    Let's face it. If you use Microsoft products, then you will have to deal with trojans, viruses, and worms. Microsoft defenders state every operating system has them, which is true. However, the risk on a Linux operating system is relatively low. Linux has 863 threats as of Jan 1, 2006. Whereas Windows had 11,000 in the second half of 2005 alone.[1]
