Students are responsible for protecting their computers from worms, viruses, spyware and other harmful programs, generally called malware. We make it simple by providing anti-virus and anti-spyware software free of charge to all students. Of course, if your computer came with an anti-virus program or subscription, you are welcome to continue using it. You should only have one anti-virus program installed at a time.
You can use the personal version of the same product we use on campus, Sophos Home, at no cost, and you can also have family members at home use that same program, up to 10 computers per account. You do not need to run any additional spyware detector or malware remover (e.g., SpyBot, AdAware) while Sophos is protecting your machine. And yes, Mac and Linux users are still vulnerable to viruses and malware without additional protection like Sophos Anti-Virus!
