Downloaded a program which surreptitiously added Delta search, which overruled Google search.
So far I have taken these steps
1. Uninstalled program using vsRevo Uninstaller in advanced mode
2. In registry searched and deleted anything of the program and Deltasearch.
3. In ZA application control changed any entry to kill.
4. In ZA set the IP address to blocked.
5. Restarted computer
Despite all this, if I click on the home icon in Chrome. say to access maps, Deltasearch rears its head in the address bar

Help, why can't I get rid of the bally thing?
