Famous Viruses

There are thousands of computer viruses floating around the internet. A new one is released every week and that's why you need to keep your virus scanner fully updated. We'll now look at some of the most well known viruses throughout history.

Melissa Virus

This was a particularly potent virus which managed to spread very quickly. It affected millions of computers and managed to spread to over 20% of all the worlds' computers. This had some very large profile victims including Intel and Microsoft. The Melissa virus relied upon a security vulnerability with the Outlook mail client. The virus worked by sending a copy of the virus to the first 50 people on your outlook contacts.

To stop the spread of the Melissa virus many mail servers were shut down. This was a very serious virus which is still seen occasionally.

Blaster Worm

This is another powerful piece of malware. This is technically a worm which means it's capable of sending itself to other people. It used vulnerabilities in Windows XP and 2000 computers. This virus can shut down your computer on a regular basis, which can make using it very difficult.
