An antivirus is a computer security software that is developed to detect and remove various types of viruses and malicious software’s (like Trojans, spyware, adware and rootkits).
Antivirus software usually used two basic methods for detecting, blocking and removing viruses. These methods include:
• Signature based scanning
• Behavioral Scanning
Because it relies on signatures and patterns, anti-virus software can only detect viruses that have signatures installed on your computer. As new viruses are written every day, anti-virus vendors provide regular updates to their product. Therefore it is necessary to keep the option to automatically receive updated virus definitions “Enabled”.
Some of the consideration for selecting the best antivirus for your computer are :
• Ability of antivirus software to detect all types of malware
• Ability of antivirus software to remove that malware
• Effect of the software on performance of computer and its efficiency
• Price of the antivirus
• False Positives (Lower number indicates better performance)
Recommended Anti-Virus Programs
Many new computers come with trial or demonstration versions of antivirus software. These trial versions do not meet SU requirements. Students need to verify that the antivirus software installed on their computer is a fully licensed version. The following free anti-virus programs are recommend by ITS.
Windows 8 comes with Microsoft Security Essentials. It is possible to disable the program, however, any non cloud based antivirus could cause performance issues if installed on Windows 8. It is the recommendation of ITS that Windows 8 computers utilize Microsoft Security Essentials with Windows 8.
Available Anti-Virus Programs (Windows)
- Avira (formerly AV Guard)

Norton Internet Security 2007 and versions beyond has proven to be incompatible with the University's new VPN service. Other "suite" security software packages that offer multiple security features may also pose a compatibility problem with the VPN service. ITS recommends that clients install only antivirus software and anti-spyware packages on their personal computers instead of full-service security suites.
Additionally, the Microsoft Windows firewall may yield better results with the new VPN than third-party firewalls.
