It's not malware, go into the Chrome settings and put the defaults back on. You will have to change the default search engine and the default home page. 

 

On Google Chrome:

 

Click 3 horizontal lines icon on browser toolbar;

Select Settings;

Select Basics ->Manage Search engines;

Remove unnecessary search engines from list;



Go back to settings. On Startup choose Open blank page

That appears to have worked. It returned once previously, but I installed a download from internet. Maybe it came back from that.

 

Thank you.
