Microsoft has finally came out with the final version of MS Security Essentials, a security software that complements Windows’ built-in firewall in XP and Windows 7 and offers antivirus, antispyware, rootkit detection, and trojans – all for one great price – free!

That’s right, you no longer need to shell out $80 each year for your (crappy) antivirus software (if you used ESET NOD32 or Avira Premium, disregard the crappy part). So what’s so exciting about another free antivirus? Well, for starters it doesn’t have annoying ads like Avira Free, offers decent detection rate (greatly improved compared to OneCare), and is pretty light on resources (about 8 Mb for me in the background).

I’ve been using the Beta for a while, and the final version (1.0) is available in both 32 and 64 bit. Quite happy with Microsoft lately. Get your hands on it while it’s hot: Microsoft Security Essentials Download
