A Google redirect virus is a type of malware that redirects your Google searches to lesser-known search engines, typically to bring advertising revenue to the creators of the malware. Remove a Google redirect virus by running a full system scan using a free antivirus program and by setting your browser's default search engine back to Google.
Scan Your Computer
Download and install a reputable antivirus application. A few examples of applications that are free of charge to download include Panda Free Antivirus 2015, Avast Free Antivirus or BitDefender Antivirus Free Edition.
Update your antivirus program's definition files to ensure accurate detection of the latest threats.
Run a full system scan and follow the on-screen instructions to quarantine malware files found by the antivirus software.
Reset Your Browser's Default Search Engine
Edit your Internet Explorer, Firefox or Chrome settings to undo any changes the virus made to your default search engine.
Click the downward-pointing arrow in Internet Explorer's address bar and select Add.
Select Google Search from the list of available add-ons.
Click Add to Internet Explorer.
Tick the Check Box next to Make This My Default Search Provider and click Add to finish setting Google as Internet Explorer's default search engine.
Untick the Check Box next to Use Search Suggestions From This Provider if you do not want Internet Explorer to display search suggestions as you type keywords or phrases in the address bar.
Click the Magnifying Glass icon in Firefox's search bar and select Change Search Settings.
Select Google from the Default Search Engine drop-down menu and click OK to save your settings.
In addition to the main default search engine, Firefox lets you perform searches using a series of alternate engines by entering keywords in the search bar and clicking the icon of the engine you wish to use. Customize the search engines used by this feature — called One-Click Search — by ticking the Check Boxes next to the search engines you want Firefox to display.
Open the Chrome menu and select Settings. On Chrome's Settings page, select Google from the Search drop-down menu.
