Virus msn

Bonjour,

J'ai cliqué sur un lien cet après-midi qui a vérolé mon pc.

Depuis, mon msn se déconnecte, me dit que je suis connectée sur un autre pc et en profite, pendant ce temps, pour envoyer le lien "happy-new-year.awesomeofferz.com" à tous mes contacts.

Je ne sais pas comment faire pour m'en débarrasser. Pourriez-vous m'aider, svp ?

Merci d'avance pour l'attention que vous porterez à ce post.
