Tips to protect your browser in the futureOnly 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. These programs can do things like add toolbars or ads to your browser.
To avoid this problem, only download programs from trusted sites.
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.
