In Windows, how do I safely upgrade to the latest Symantec Endpoint or AntiVirus software?
To best protect your Windows computer from viruses, you should use the latest version of protection software available for your computer. At Indiana University, both Symantec Endpoint Protection (SEP) and Symantec AntiVirus (SAV) Corporate Edition are freely available to students, faculty, and staff via IUware. Symantec Endpoint Protection is the newest Symantec AntiVirus product, combining technologies from the previous Symantec AntiVirus and the ability to protect via behavioral analysis, thus allowing Endpoint Protection to stop some threats without an actual virus signature.
Important note: When you upgrade your Symantec software, it is very important that you follow the procedure outlined below. If you simply uninstall your current antivirus software and then reinstall the newest version while your computer is connected to the Internet, your computer will be vulnerable to a virus or other malicious attack during the time it is connected to the Internet with no antivirus software. It can take mere seconds for your computer to become compromised while in such a state. Thus, UITS strongly recommends that you use the procedure below to update your antivirus software; you will find that it is not difficult to follow:
