Tips to protect your browser in the future

Only download from sites you trust

Sometimes you download a program you want, but the program also contains bad software. Even though you can see and use the program you wanted, the bad program might be running in the background, adding toolbars or ads to your browser.

To avoid this problem, only download programs from trusted sites.

Carefully review updates for your extensions

Safe extensions that you already have on your computer are sometimes purchased by hackers. When you update the extension, they can install malware onto your computer.

To prevent this, always read through the update notification carefully.
