I am assume that you are talking about computers...running Windows.

There are many types of virus/worms that can attack your computer. Most virus are self contained little programs. Usualy with malicious intent. And worms are usualy bits of script written with Microsoft Word or any script editor. Worms usualy do the same, but are easier to transmit via the internet.

The best defence in my oppinion is to have an up to date Virus Scan program i.e. Nortons, McAfee, etc... and a fire wall i.e. Norton, McAfee, Zone Alarm, etc...

And the MOST IMPORTANT thing you can do is update Windows with Microsoft updates. Also you should update Internet Expolrer, all the Microsoft Office software, and any other software that you can update.

Do a search and research programs that can block, stop, and delete virus/worms.

Here is one place to start http://update.microsoft.com
