Chrome is less susceptible to browser hacks currently, it sounds to be that you have a IE browser hack possibly. you might be able to click on tools, internet options, then the advanced tab, click the reset button to reset ie back to default. apply, ok. close ie, then reopen ie and see if that fixes the issue. if the issue persists see if you can download ccleaner from piroform.com and or spybot search and destroy from safer-networking.org
