Hi Brett, I I will help you with the issue, may I know which AVG program have you installed in your computer ? and did the AVG program detect the virus when you scanned your computer ? Please elaborate how did you find the virus in your computer ? Please let us know and we will solve the issue,  Thank you

I have used malwarebytes, hitman pro, etc. to remove Trovi but nothing working.   Just renewed AVG 2015 for $50, but questioning that move now that Trovi still present.  please help

Hello Brett,
I apologize. I request you to please try the below steps. To set Google Chrome default search engine from Trovi Search to Google. Click the Chrome menu button, then select Settings and click on Manage search engines in the Search section. In the Search Engines dialog that appears, select Google and click the Make Default button that appears in the row. feel free to get back to us. Thank you.

Hariharkumar,
Thanks for the reply.  
1.  AVG Anti Virus 2015
2. did not detect Trovi virus
3. I have 3 home pages that open up when I start Google Chrome. Now when I start up Google Chrome it only has one page, the Trovi search page.  Malwarebytes did detect and I thought it removed, but once I rebooted, Trovi came back.  Hitman Pro detected and fixed, but then on reboot, Trovi came back.  AVG 2015 has never detected.
Thanks,
brett schroyer
