Computer viruses are small software programs that are designed to spread from one computer to another and to interfere with computer operation. No computer system is immune to malicious software. Viruses can be installed on a machine unknowingly and involuntarily and are spread through emails and internet downloads where they can be disguised as programs or multimedia files. To protect your computer it is important that you keep your computer updated and have an antivirus program to prevent it from getting infected.
Some virus protection software is free others are not. All Windows computers in the labs and offices have Microsoft Forefront installed on them. The College does not provide virus protection software to students, but it does recommend using Microsoft Security Essentials, which is free to download from the Microsoft website.
There are other software known to remove different types of viruses such as Antimalware byte or Microsoft Safety Scanner. A complete list of commercial antivirus vendors recommended by Microsoft can be found here.
Before you install antivirus software, check to make sure you don't already have an antivirus product on your computer. If you do, be sure to remove the product you don't want before you install the new one. It can cause problems on your computer to have two different antiviruses products installed at the same time.
