A virus is an unwanted computer program that gets on your computer without
your permission. It can do anything from being a nuisance that pops-up
messages to causing crashes, erasing data, and destroying motherboards.
There are many different types of viruses that are passed in different ways,
just like the real, biological viruses. For more information see

There are other antivirus companies as well.
