To protect your personal computer from viruses, Butler Information Technology recommends using the built-in security software provided with the operating system. Both Windows and MacOS computers come with built-in security software. Windows 8.1 and above includes Windows Defender, and Butler IT recommends Microsoft Security Essentials for Windows 7 computers (download free here).

If you would like additional protection, Butler IT recommends Sophos Home Edition (download free here) for both Windows and MacOS. Never use two different antivirus applications at the same time.

Computers found to be infected by a virus will be removed from the network due to the security risk(s) they pose.
