A recently found flaw in Internet Explorer left every version of the browser since IE6 vulnerable to attack. Microsoft fixed the problem and released an emergency patch to secure the flaw. If you’re on a Windows-based machine, you should receive the patch automatically. But if you want to double-check and make sure your browser and computer are protected, here’s what you need to do. Head into Windows Update, which you can find within your computer’s Control Panel. Click the button marked “Check for Updates” to force your computer to scan Microsoft’s servers for the latest patches. The update you’re looking for is clearly marked as a security update for Internet Explorer. Check the box next to that update, then click “Install Updates.” Restart your computer and you’re good to go! This security update was rolled out for every version of windows back to – and including – Windows XP. So if you’re using a computer with XP, Vista, Windows 7 or 8, make sure to download the update to ensure your computer’s security.
