If you're still having issues, I recommend doing these things. Download SAS, or SUPERAntiSpyware, and install it. Once you have it open, run a "Complete Scan". This will remove any spyware, adware, malware etc., you have on your PC. Once that is done, open Chrome, go to Settings, scroll to the bottom and select "Reset settings". Once you're done, you should be fine.
Note: If you have anything important on your browser, any tabs pinned for example, you should back that all up. Also, I've had issues such as this a lot before, and this is what always worked for me.
