Search Encrypt is a browser extension that somehow got added to your computer. It's an accessory for the browser of sorts. Depending on the browser, find the place where add-on's or extensions are managed, and remove it from the browser.
Another place to check in the browser is the default search provider, switch it back to Google or your preferred (legitimate) search engine, and remove the Search Encrypt.
It may be even easier to use the Programs And Features in Control Panel to select it an uninstall it (if it shows up there, fingers crossed).
Remember fellas, a lot of people search using the address bar which processes through your default search engine for that browser. You can also go to the search website and use their place to type your request.
