"rundll32 has stopped working" Upon launching websites like youtube

I've been having a strange issue lately and i'm not too sure where it has come from. Everytime my computer starts up my desktop icons and taskbar doesn't work. I have to hit ctrl + alt + del and then hit cancel in order to unfreeze them.

Everytime i try to launch a website like youtube or any site that has media players, i get a "rundll32 has stopped working" at the website's launch. Then when i try to open the videos on the websites, the "Play" icon is off to the side where it normally isnt, and i cannot play the videos.

Basically my browers have been super glitchy after this. An example is when using google chrome whenever i hit the "previous page" button, it opens another tab instead, and when i click on that tab it closes it. Anytime I try to click another tab it just closes it. This also has a strange effect on my VLC player, none of the buttons work, i have to right click and use the buttons that way. I've never seen anything like it before.

Hello ripabbott and welcome to Seven Forums.

The first thing I'd do is run a full scan with your antivirus/antispyware of choice. Then I'd follow up with a couple of free on-demand scanners that have a good track record of finding things that others miss. One is Malwarebytes and the other is HitmanPro.

It's also possible that you might have some damaged or corrupt system files. Try running a System File Checker scan from an elevated command prompt (option two, this tutorial.) If any problems are found, run the scan three times rebooting in between each scan.
