Last week you may have ready about a zero-day exploit (Security Advisory 2963983) that affect all versions of Microsoft’s Internet Explorer, from versions 6 through 11. It was considered to be pretty severe, with government agencies even suggesting changing browsers. The exploit allowed for hackers “to execute arbitrary code in the context of the current user within Internet Explorer” if they surf to a website coded to take advantage of the browser hole.

Yesterday, Microsoft released a patch through Windows Update and even offer it for Windows XP users, even though support for that operating system ended on April 8th.

Even though most computers will update automatically, I would recommend going into Windows Update and manually updating as soon as possible, even if you don’t use Internet Explorer.
