The Norton Virus Protection is protecting against 47,638 viruses. There are an average of 15 to 30 new viruses each week added to the definition list. The KAK/WORM virus is the least of your worry. The Trojans are even more sneaky. Some once installed on your computer will allow a malicious operator take over your computer and do a lot of strange things. They can send e-mail to every one on your address book from your address. This is one way they can "spread" the virus. Go to http://www.datafellows.com/v-descs/subseven.htm as one example. It will list all the things that these Backdoor type Trojans can cause. I do not intend to abuse the rules of this list by continuing this subject. This problem is not going to go away and we must learn all we can to protect ourselves. These hackers are not content with just playing high tech war games. As I mentioned before, we all have too much at stake to loose all our records and put up with crashes and other computer non-sense. My last comment on the subject but will clarify or answer questions. Robert Crabtree
