2. Microsoft Security Essentials

Microsoft Security Essentials
  • Rating: ratingsratingsratingsratingsratings
  • Reviewed on: 8 December 10
  • RRP: Free

There's a lot to like about Microsoft Security Essentials, but we were a little disappointed by its malware detection and attack blocking - after all, antivirus software is only as good as its ability to keep your PC protected. Hopefully, Microsoft will bolster Security Essentials' threat-blocking capabilities in a future update, but until then, you'd be better served by going with something having better detection capabilities, such as Avira AntiVir Personal.
