Sorry if this is a little off topic, but I'm seeing a lot of people still using Windows XP. Beginning April 8th, 2014, Microsoft will stop supporting Windows XP, and you will be at risk to many security threats. No matter how good your antivirus is, if an OS isn't patched regularly, there is a high chance of being affected (and considering the number of users still on xp, hackers will specifically target XP users after Microsoft ends support making you all even more vulnerable). I'd highly recommend XP users to migrate to Windows 7/8 ASAP!
