Using latest version of chrome. When I open my homepage a 2nd page in a new tap is opened as well:

I have reset chrome, run malware scans, reinstalled ccleaner nothing works.

How can I stop this from happening?

nothing to do with your browser or CC, that address is simply not working.

happens here on my Firefox as well.

take off the /ccleaner part and see the error message, that may explain it for you.
