Microsoft has issued a warning of a new security bug that affects Internet Explorer 6 through 11, one that leaves people still hanging onto Windows XP extremely vulnerable. The bug, a zero-day exploit, makes for a potential virtual gateway. Should you happen to visit a malicious websites, hackers can theoritically take over your computer remotely. While Microsoft is busy working on a patch for its users, XP users have been left high and dry. With support for the 12-year-old operating system having ended a few weeks ago, there will be no critical update for anyone clinging to Windows XP. To put it bluntly, there has never been a time for XP users to stop being stubborn and upgrade their OS to one less likely to be exploited by hackers.
