IE has many more exploits than Chrome. You can get viruses from ads even on major websites. I got a virus from an ad on Firefox when I was on Wikia! I just went on a page, and BAM! My browser froze up and a virus downloaded itself on my computer! Fortunately, I wasn't on the administrator account at that time, so the virus couldn't do much. If I had been on the administrator account at that time, my computer could have been badly messed up. I still had to do a system restore after that virus...

Anyway, Chrome has many features to protect against exploits like this. Each tab is a separate process, so a script running in one tab cannot infect your whole browser. Stuff like tabs, plugins, etc., work at very low privileges on Chrome, so malware has a much harder time installing itself.
