You are using AVG for your anti-virus software, and now every time you open your web browser, AVG Secure Search is your default page. This may occur in IE, Chrome, Firefox, etc.
AVG has a webpage dedicated to disabling AVG Secure Search. The exact steps differ depending on the web browser in use (refer to the link just listed).
I found that the instructions for Chrome are a little off. For the most recent version of Chrome, do this:
- Start Chrome.
- Open a new tab.
- Click on "Restore default new tab" in the far upper-right.
- The AVG Security Toolbar Settings will appear.
- Deselect "Show AVG Secure Search Box on new tabs in the browser".
- Click Ok.
- Restart Chrome.
