Computer Security Advice

Viruses, worms and trojans pose the biggest security threats to computer users today. They spread easily between unprotected computers. PCs running peer-to-peer software are most at risk. Google and Yahoo! style toolbars are also routes in for this kind of malicious software, sometimes known as malware.

Protect Your Computer

In order to connect to the College network you are required to have anti-virus software, anti-spyware software and a firewall. Lower risk operating systems such as Mac and Linux are still required to have all of these pieces of software in place as although there are a very small number of viruses which affect them, they are able to contract a Windows based virus and pass it on through the network of primarily Windows based computers.

It is also important to keep up to date with patches and updates for the operating system. These important security patches repair flaws in the operating systems which may allow your computer to be vulnerable to any kind of malware. Fully updated operating systems are also a pre-requisite of being connected to the College network.

Hoaxes

Never believe the emails which circulate asking for bank details. Your bank will never ask for personal information via e-mail. If you are in any doubt, contact your bank by phone using the number provided on their official website, rather than any contact information provided in the e-mail.

Another common hoax is an e-mail or browser pop-up informing you that your computer has been infected with viruses or spyware and to click a link to download some software to remove them. An e-mail or browser pop-up cannot have gathered information about the state of your computer and these links moreoften than not are links to viruses or spyware. Only trust information about viruses or spyware from your virus scanner or spyware scanner. If in doubt, contact an SCO or Computer Officer for confirmation.
