search engine problem

Well sounds like you might have a virus problem there, have you scanned it for viruses? If it isn't a virus problem, have you checked if any other browser works good when searching? Maybe you installed an extension or add on on your browser that causes it.

I think you have a malware or an adware on your system. A good spyware removal software should do the trick. What I usually use is malwarebytes, its good, light weight and it should fix all of your issues related to a malware or adware. The best part of it is that malwarebytes is free.

it happened to me too. what happened was that a change was made in my toolbar by a virus presumably. so i cleaned my laptop by removing all history, caches, cookies, downloads in the hope that the virus would be removed as well. i also checked the settings if some suspected virus is staying in my system. scan and delete the virus in your system.
