Recently I've been receiving so many SPAM mail on my Facebook's wall. You know, like video saying I Found This and some sort of other things. Then, my friends said not to open or click the links given as it contain virus & may affect the computer. Here's a snippet on how you can handle this matter:
Problem: LOL. Look at the video I found of you!
This is the most dangerous of all the spam messages and it comes in a variety of forms, says Clare. It's actually a bid to surreptitiously install malware on your computer. This malware can track your computer keystrokes and record your sign-in and password information with all of your online accounts.
How does it work? When you click on the link, it says that you need to upgrade your video player to see the clip. If you hit the "upgrade" button, it opens your computer to the crooks, who ship in their software. You may be completely unaware of it until you start seeing strange charges hit your credit cards or bank account. Up-to-date security software should stop the download. If you don't have that, watch out.
Better yet, if you really think some friend is sending you a video clip, double-check with the friend to be sure before you click on the link. When I messaged my high-school classmate to ask if she'd really sent this, she was horrified. Her Facebook account had been hijacked and anyone who clicked through was likely to have their account hijacked too. That's how this virus spreads virally.
