A hijacked browser plagues you with endless pop-ups, uncontrollable URL redirections and general software instabilities. Hijacking is caused by a particular type of malware, which can sneak into your system through a cleverly disguised link or downloadable file. If your installation of Google Chrome has been hijacked, you need to act immediately to get the infection cleared off your system. If you are having difficulty keeping Chrome open to a particular page, you may want to open these instructions in a different browser.
Exit Chrome. If pop-up windows appear too quickly for you to close your browser, you can manually shut down the program with Windows Task Manager. Press the Ctrl, Alt and Delete keys, then click "Start Task Manager." By default, the "Processes" tab will be selected. Select "chrome.exe" from the list of running processes. Click the "End Process" button. All Chrome windows will close.
Run a full scan of your computer using your antivirus software. Once the scan is complete, follow all quarantine and removal instructions for detected malware.
Restart Chrome. Click on the wrench icon in the upper right corner. Select "Options." Return your home page settings to normal. A browser hijacker may select a new home page.
Click on the wrench icon. Select "Tools," then "Extensions." Uninstall all recently installed extensions. A browser hijacker often installs itself through a third-party extension.
To help prevent browser hijacking in the future, configure your antivirus software to enable real-time protection.
