Windows 7: Internet Explorer slowed down after Chrome installation

The other day I installed Google Chrome from the link that appears in the Google home page(you have should seen it). And for my surprise, instead of download a setup file, it's like it has installed from the browser, of course it should had downloaded some temporary files. The point is that after the installation, internet explorer took much time to load any page exept google one. So my conspiration feelings worried me, hahahaha. Why is my internet explorer slowed down after that installation? It's just a coincidence? No complement seems to be the reason... Any suggestion?

Oh yes, I have seen that annoying download google chrome box every time I open up the google home page with ie9. Surprisingly when I open up google with firefox 4 I don't get the chrome download box. I'm not sure if FF is blocking it or what, but it's nice not seeing it.

I would uninstall Chrome to test if it's the reason for your IE9 slowdown.
