AntiVirus and Malware Information

Per UCSC policy, all laptop and desktop computers connected to UCSC's network must run current, up-to-date software to detect viruses, spyware, and other malicious software. Anti-malware software is recommended for other devices where readily available and as appropriate.

Windows Computers

For students running Microsoft Windows, ResNet recommends Microsoft Security Essentials. Microsoft Security Essentials provides protection against viruses and other types of malware for free. Microsoft Security Essentials can be downloaded via the Software pages at:

As a secondary antivirus scanner we recommend using Malwarebytes, also called MBAM for personally owned machines. This is a free non-active scanner, meaning that it will only scan when manually started. It is a great compliment as a secondary scanner and will often help clean out malware that your primary scanner may not catch. Malwarebytes may only be used on personally-owned computers.

Note: Having multiple active anti-virus scanners installed and running simultaneously can create conflicts and slow down your computer. Some vendor products are also known to conflict with the ResNet environment including: Norton AntiVirus, McAfee AntiVirus, and their Internet security software. These software applications may block your computer's network access and create the need for additional troubleshooting.
