I sure do have great timing. Looks like there is a very serious vulnerability in Internet Explorer versions 6 - 11 which could allow a total hijack of your PC. Sounds like this vulnerability has been exploited in the real world.

So, if you're an IE user, use something else for a while until this gets addressed. People still using WinXP are probably out of luck on getting this fixed, though, which is basically what "everyone" has been warning about as XP support ends from Microsoft. No more fixes and updates for the XP users.

Some articles mention that this is a Flash-based vulnerability, but I think they are mixing up two separate issues. More info on the IE issue can be read here .
