Instant messaging being hacked

Well im a frequent user of yahoo and my friend was sitting at my computer and she was getting constant messages along with the messages of the person she was talking to.
she clicked the link and it has happened on even ID that logs into that yahoo, even when i have created my own chat room etc
the link that keeps writing automatically from my messenger along withmy messages is " 53best. com" i dont recommend anyone to open the link.

If anyone can help me get rid of this annoying message. i would appreciateit greatly.

Thanks in advance.

  1. If you don’t recommend anyone open the link then I suggest that you edit it so that it is not a clickable link, leave of the www. and simply put 53best.com

  2. What version of avast are you using, have you got the IM shield enabled and set-up for yahoo, etc.

  3. As to getting rid of it now your are infected, I would suggest a visit to Eddy’s Website click the “HiJackThis Section” and also the “Malware removal instructions and applications” section, and follow the directions there and get back to us if you need more help…
