Norton (very popular anti-virus software provider) has a web-application called Norton Safe Web for Facebook which assists in fighting these threats on Facebook. Like all other Facebook apps, it will ask your approval to install. Click on 'Allow'.
On the subsequent screen it will ask for additional permissions to access your posts, timelines etc to scan them for any infections.
One it has scanned your profile it will show the results as below. It may take some time depending upon how active you are on Facebook and how much work it has to do to search all your posts, timelines etc.
You also have the option on enabling auto scan so that you don't have to run the scan frequently. It is a free application.
