An introduction to viruses

It's email that's most dangerous, especially email attachments. The virus sender may even be somebody you know and trust, because the virus can send itself using their name and address.

There's no substitute for running virus protection software. You'll also need to periodically update the data file that comes with the program so it's able to recognize new viruses.

If you don't do this, and you open email attachments, you will almost certainly catch a virus at some point.

Even if you run a virus protection program properly, you're still at risk when a new kind of virus comes out, because your system won't recognize it.

So you still need to be careful when you open email attachments.
