Could somebody tell me exactly what a "worm" does? Does it affect getting into web sites? I've been having trouble accessing just about everything lately. If I click on something like Bonnie's "Air Plane Joke" I get shut down and have to hit Ctrl/Alt/Del. The same goes for some web sites. I can access a game I have on my favorites list and a couple of other game sites. I don't pretend to understand any of this, but I was wondering if this "worm" everyone is talking about could have something to do with it? I know I need to Purge Cache every so often, so I did that last week, but it didn't help. My computer is old and SLOW, but this is getting ridiculous, not to mention irritating. Any help would be greatly appreciated. Eleanor
