Microsoft Security Essentials review
With support for Windows XP now ending, many people are concerned about whether their computers are still secure. Some of those people will also have been relying on Microsoft Security Essentials to protect their PC, as it's freely available.
The good news is that Microsoft will continue to support the XP version of the software up until July 2015. The bad news is that is was never much cop to begin with, with other free anti-virus options performing far better in our tests, and even a Microsoft employee admitted it was supposed to be a 'baseline' product.
Instead we'd strongly recommend you go for Avast! Free Antivirus 2014. It's easy to use, unobtrusive and offers better cover than other free software, but it still can't match the best paid software for protection, so also strongly consider Kaspersky Internet Security 2014.
