Run Malwarebytes. Should remove it. If your browser is still stuck on the coldsearch for search engine then try this.

Restart the browser and check it should be removed.

@Karadjgne,

Your advice is like curing a headache with a guillotine... If that problem is hidden into group policy, Microsoft provides a tool for that. I have Chrome browser installed, and there's nothing Chrome-related in these folders, but a lot of other info one would lose (and develop other problems).
