Free anti-virus software

Security software, combined with careful browsing online, is the best form of defence from internet nasties. Check out our guide to security software for more advice.

The biggest names in security software are Norton and McAfee. Their security software suites have been big-sellers for years, and while they are both include a comprehensive set of tools to help keep you safe, sometimes a free anti-virus program like Microsoft Security Essentials will do the job.
