Exploiting browser vulnerabilities has become a popular way to compromise computers.There are several easy ways to secure your preferred browser, through individual browser settings and add-ons. Browsers aim for a balance of performance and security. Features added by the manufacturer to improve performance may make the browser (and the computer) less secure. In addition, the more add-ons you have installed, the more your browsing experience may be impacted or slowed.

- If you have Adobe Flash or Oracle Java plugins installed, consider uninstalling them. Many content providers have moved away from these platforms due to ongoing security issues with both.
