With so many malicious apps(applications) on Facebook, you may have unknowingly installed or given these applications access to your Facebook account. These malicious applications can post links on your Facebook Wall or your friends' Facebook Walls to malicious websites that can infect your computer and steal your username, password, credit card, and other personal information.
Here is an easy way to view all your Facebook applications and remove the ones that you are not familiar with:
- Ensure that you are logged into your Facebook account.
- Click here to go to your Facebook account settings
The link will take you to the Facebook application settings page and list all the applications that you have given access to your account (see image below). If you are not logged into Facebook, you will be redirected to the login page; just login to continue.
Move your mouse over the application and click the "X" or "Remove" button when it appears, to delete the application (see image above). Once the application is removed, it will not have access to your Facebook account anymore.
Remember that malicious applications can use popular names like “YouTube”, “CNN”, and “MSN” to trick you into believing that they are legitimate.
I recommend that you remove all the applications if you are not sure which ones are legitimate.
