Windows10 is great... turn off a bit of the crap and its much better than 8.....
Rowlf do you have a virus killer AVG/AVAST? do a scan...
also try malwarebytes
https://www.malwarebytes.org/ and check for malware.. WIN10 is NOT your problem...something else is
Also.. are you using GOOGLE as a browser (EXAMPLE: GOOGLE CHROME) or are you using it to search (EXAMPLE: USING CRAPPY INTERNET EXPLORER AND GOING TO GOOGLE.COM) sorry for what might appear to be stupid questions...
