Problème de lien google

Bonjour,

Depuis quelque temps, j'ai des petits problèmes avec google. Si je fais une recherche, google me sors bien des résultats cohérents. Cependant, une fois que j'essaie de cliquer sur un lien il ouvre un nouvel onglet et me redirige vers une page qui n'a rien a voir avec ma recherche.

Je voudrais donc savoir si quelqu'un pourrait m'aider à résoudre ce problème.
D'avance merci

Configuration: Windows XP
