Plantage du pc apres ouverture d'explorer

Bonsoir a tous. Je n'ai pas l'habitude de ce forum et suis peu callé en informatique donc veillez m'excuser et m'informer si des indications manquent.
Voila le soucis: mon pc redemarre des que j'ouvre internet explorer.
Malgré l'installation d'un anti pop-up, l'utilisation frequente d'anti spyware (spybot, ewido, ad-aware,...), le bon fonctionnement du fire-wall (zone alarm) et de l'antivirus (Avast), le probleme persiste.
Je pense donc que le probleme est plus profond et espere qu'une ame charitable aura la gentillesse de me sortir de cette situation.
Je vous en remercie d'avance.
