You should always make sure you have antivirus software installed on your desktop/laptop and keep it updated regularly.
Given the number of ways in which people (often with criminal intent) try to install malicious software on computers these days, all of them, including Macs as well as PCs, need an anti-malware solution installed and kept up to date.
Bangor University-owned computers
The University has a site licence for Sophos Anti-Virus, which covers all University-owned computers. Sophos should be pre-installed, should update itself automatically and must not be interfered with. Windows computers now also have Sophos Intercept-X installed which gives protection from ransomware and other so-called “zero-day” exploits which attempt to use newly identified vulnerabilities.
Your own computers and laptops
PCs with Windows 10 installed should have “Windows Defender” installed as part of the operating system and this helps guard your PC against viruses and other malicious software. Users of these computers don’t need to do anything else.
For a more advanced solution, users of both Windows and Mac computers can install the free “Sophos Home” product from https://home.sophos.com/. According to their web site:
“Sophos Home protects every Mac and PC in your home from malware, viruses, ransomware, and inappropriate websites. It uses the same award-winning technology that IT professionals trust to protect their businesses. Best of all, you can manage security settings for the whole family—whether they’re down the hall or across the world.”
PLEASE NOTE: The University licence for Sophos no longer covers computers owned by staff and students. Anyone who has downloaded and installed Sophos from the Bangor web site should remove it and install one of the replacements suggested above. Updates for this are no longer available.
