Une sale bête nommée spads.dll

Bonjour,
lorsque j'allume mon ordinateur un message d'erreur de rundll apparait, j'ai manifestement un soucis avec spads.dll. Est-il jusdicieux de l'effacer carrément de l'ordi ou serait-ce une grosse bêtise?
A l'attention aux connaisseurs en informatique, pourquoi n'expliqueriez-vous pas dans un topic comment vous faites pour interpréter les rapports hijackthis? Personnellemnt le débutant que je suis n'y comprend absolument rien. Parenthèse fermée je vous remercie d'avance si vous avez la solution à mon problème!
