I guess it is if you download a bad app, you should use common sense and only download apps that are from reliable sources and make sure you have a good antivirus installe don your computer (I have Unthreat Antivirus and I really like it).
"I'm seeing a lot more of my friends falling prey to Facebook viruses latley so I thought it would be a good time for some simple reminders on how to avoid them. Technically speaking, most of the "infections" you get on facebook aren't often virusus at all but they can be equally malicious and for the sake of simplicity we'll just lump them all under the category of viruses.
These often appear on your wall in forms of a bizarre or eye-catching stories and videos and once the user has clicked/liked the link, it is already late. The next step will be getting rid of your"infection" whichcan be a time-consuming process. Its better to avoid spam messages and trojan viruses in the first place"
