When I opened my Yahoo Messenger a while ago, I received an offline message from a friend linking to an image. I am so excited because yesterday, we had a picture taking in the meeting and I thought that link will bring me to our pictures. To my surprise, the link brought me to a page that contains advertisements and in an instant, my browser was behaving badly and my task manager was disabled. When you paste a text in notepad or any page, the following message will appear:

:D who is beside you in this pic http://thecoolpics.com/friendpic1.jpg so good-looking

I reboot my computer and to my horror, my Yahoo Messenger automatically signed in with different yahoo id and password. When I changed the id and password, the messenger automatically sent messages to the people in my phonebook linking to the site where I got the virus.
