Impossible de supprimer une pub internet, svp, aidez moi

Bonjour, si je poste ce sujet ici, c'est que je ne sais vraiment plus quoi faire... Je sais pas ce que je me suis attrapé, mais ça me souligne 60% des mots d'un site ou autre en vert, et quand je clique dessu, ça m'enmene ici: http://onlinewebfind.com/ads-clicktrack/click/newjump1.do?affiliate=63659&subid=advertisewp11&terms=personnes&rtw=rpg%20paradize%20serveur%20priv%20mmorpg%20minecraft%20dofus%20daoc%20wow%20dark%20age%20of%20camelot%20world%20of&ai=_4Np0tDKT2v3e5mY34AvOl3szq1ATM34Bp0Yf_gndqyeFu41Kze3vu6NQUC5O5wJUkBGJpujO3GM2qWXnkpG5sh2NnE3CMixGQuobH-W2tRmIprZdyKkpn-RLdTMMzzhEy3VqEKfmfV9QulgvA8Y61GNsKeTu8EeJuzohVy6hG_wduPsz-QqYyUb9eHDOUzAi769vJdPC6dLwdOkN0zeh-SkB_hmu6wM5FDVwOcGfrOnrNv-zuKXkeZm_UWx9-ohkIdolU2eu-x8a6Zstebs_SFlYH2I_7VBE2-4gbZ6Ja_Sd-pgbxEb1ljsJkTl6Fru3j-bag-lnXIJilp-eaV2zFGjsVyQAdRiD2nLevuElWw&product=intext

Et voila.. J'ai fais un Ccleaner, analise du systeme avec norton, rien... et, quand je vais ici :
http://onlinewebfind.com
Ca marque :

1. What is onlinewebfind.com?

onlinewebfind.com is an advertising network technology tracking domain. Advertisers distribute their ads across a broad network of search partners and content sites. Before traffic is delivered to advertisers, onlinewebfind.com is used as a network referral ID to identify and qualify traffic sent by traffic partners.



2. Why am I seeing onlinewebfind.com on my computer?

Because the advertising network is comprised of thousands of traffic partners, you may have been included within a partner's advertisement distribution network. If you have received any advertisements that contain the url onlinewebfind.com, it is important to understand that this property and the advertisements you've seen have no association with the traffic partner that is displaying ads to you. onlinewebfind.com is not the source of the advertisements.


Donc, voila.... si quelqu'un pourrait m'aider... Car c'est hyper chiant.. je passe juste le souris sur un mot, ça ouvre un truc, et ça met "click here"
