Computer viruses are small software programs that are created to spreasd from one computer to another and to disrupt computer operation. A virus can easily corrupt or destroy data, your computer, use your e-mail program to spread itself to other computers, or even erase everything on your hard disk.
Viruses are most easily generated and spreaded by attachments in e-mail messages or instant messaging messag. It is very important that one never open e-mail attachments unless it is known who is sending it. Viruses can be disguised as attachments of funny images, greeting cards, or audio and video files. Viruses also spread through downloads on the Internet. They can be hidden in illicit software or other files or programs you might download.
In order to prevent viruses, it's important that one keep their computer new with the latest updates and antivirus software, stay informed about threats you must follow to avoid viruses. Always follow tips to prevent viruses that pop up on computer screen. Once a virus is on your computer, its type or the method it used to get there is not as important as removing it and preventing further infection.

Viruses are huge problems when they occur on your network. You all may remember "msblast" or the "blaster worm." When this hit, any machine connected to the network that didn't have a particular security patch from Windows was affected. This meant we had to physically touch MANY machines in our district, literally hundreds, to remove the worm. When even one machine had it, it would cripple the entire network.
I've also encountered a virus that came in through a hotmail email account that would "eat" any executable fies on the machine---as well as on any of the machines mapped drives!!!! This meant that because they were mapped to our server, it "ate" all the executables on the server!
Oh, must I conjure up these memories! Bad stuff. We learned some lessons though.
It was a good point to remember never to open an attachment from someone you never know. Also, viruses can come from spam mail, as well. I personally keep my Norton antivirus updated to prevent such problems. Good post, Jarrett.
