Hackers rely on the fact that many computer users fail to install software patches on their machines and create worms and viruses to exploit unpatched systems. Most software vendors, including Microsoft and Apple, offer updates to correct program flaws that malicious programs use to attack your computer. Running an Anti-Virus is not enough.  You can configure your computer to automatically seek out updates.  Most College computers have been configured to do this automatically; however, if you have questions please contact the help desk.
