Internet browsers can become hijacked if your computer is infected with a virus or trojan. Unfortunately many innocent websites are filled with adware and bloatware, which can alter a person's browser settings without their knowledge. Additionally, many websites intentionally program themselves to change a user's settings. Because of viruses and spyware, it is important to have a properly
. configured virus scanner such as Norton or MacAfee. Many times, these virus programs can detect changes to your browsers settings and then revert them back to normal if they become changed. While most people can't prevent hackers from trying to hijack their computer, they can take the necessary precautions to make sure they don't visit suspicious websites. You should never click on random links, or view emails with attachments unless you know who they are coming for. Additionally, if your browser has been hijacked you can install a program called "Hijack This" to remove it automatically.
