"Hi, I'm Robert. Today I will explain what computer viruses are. A virus is a piece of software that attaches itself to a real program. And example would be a virus would attach to an actual application. And every time that application is run, the virus would also run and this could cause significant damage on your system. Another way of virus travel is through email attachment. And example would be the Melissa Virus. The Melissa Virus brought down a lot of system when it came out. Microsoft has to actually shut down their mail server because it was just so bad that they need to shut them down and stop the spread of this malicious virus. What it does is, it is a word attachment and when you open it up it just propagates and continued to spread on other, on your contacts, and every time you create an email it actually goes in to that new email that you created. So you can only imagine how fast this virus spread. This could also cause a performance issue on the servers, on the mail servers specifically. You can protect your system by installing an anti virus software such as MacAfee or Norton Anti Virus. But you just have to make sure that you update your virus definitions on a regular basis."
