A Kill Filter as hinted upon eliminates virus by removing know elements or virus. However, just like thief's. Virus authors (programmers) will come up with new stuff to get around your filters. But you still need to use those filters, as they will remove the ones that are known.
Your newsgroup provider filters out (deletes) all messages from ISP's and IP's that are known virus spreaders. Plus they scan the incoming messages for virus. But scanning only works so far, because you can still find virus. So you must rely on your newsgroup reader, which has the ability to delete certain messages from a keyword in the header. By all means use it, and scan for words associated to money, teen, test, sex, and even certain symbols. This filters out a lot of standard junk (spam) mail or posts.
