"Hey, I have some cool video of you bad work . It's very bad and your mood cool!. Check it out now"



When you receive  massages like this from facebook friend or facebook wall post .What do you really do?
This massage can be a attack of"Koobface" virus. "Koobface" comes through an e-mail sent from some of your social networks or it can be a wall post or massage that send by your friend.some are invite you to check out a video .The massage say that this Invite from your friend.And play this video.Then you trying to playing it.Then It say that player haven't on your browser and install it now.When you install it to your computer.Your computer can be get some Bot-net(a collection of  computers that control by a bot-net harder) attack.
A bot-net can get your information files & Control your computer as bot-net harder want without your permission.(see the image to get some idea)

Some  of another Massages that say that facebook found some big virus from your computer and install this software for scan and remove it now.If you install these software you can get some attack.So be careful!.
Do not accept to any unknown software and any massages that send from your friends.Becouse the can be some virus or some attact.
So be careful when you brows internet and don't accept to install unknown software .If you want to download some software.Download them from original(to download fash player for your browser go to adobe.com).
Now some post auto post when you click on the post link.And then it go round around your friends and if some friend click on it .Again it goes around on his friend.This can be damage to you.Because friends can that's doing by you and friends can be block you.So be careful when you click on links.
