How do I change my search engine?

[Eva Shah]

Which browser do you use? If you are using Internet Explorer, go to Internet Options. In the "General" tab, you will find the options to change your search provider. Try to change your search provider there first.
If you can't change it, you can be sure that there is a malware infecting your computer. Scan your computer with a good antivirus and antimalware. Remove that malware, and the search provider will be changed automatically.
