Salut,
 
Tout d'abord j'ai parcouru le forum mais je n'ai pas trouvé exactement mon pb...
 
J'ai régulièrement des erreurs svchost.exe qui m'empêchent après tout copier coller, tout déplacement de fichiers...
Mon Pc redemmare tout seul mais moi je n'ai aucun message d'alerte windows avant le redemarrage...
 
Je suis en réseau au boulot et il n'y a pas que mon Pc qui fait ça ...
J'imagine que c'est une variante de blaster mais norton fix blast n'a rien trouvé, stinger non plus, j'ai executé HIjackthis qui a trouvé que je faisais plein de logs sur des sites de Cul et que j'avait pas mal d'espion j'ai nettoyé  tout ça via HIjack mais mon Pc redemarre encore...
Le redemarrage ne se fait pas toutes les 5 min. ou toutes les 30min...mais j'ai quand même redémarré 2 fois aujourd'hui...
 
Et Les jours où svchost se met à planter ce qui m'oblige à redémarrer pour pouvoir a nouveau importer, copier,coller depuis illustrator ou Photoshop c'est l'horreur...
 
En + mon ordi rame souvent  
Please help, je sature...
 
Merci

une recherche un peu approfondie t'aurait permis de trouver quelques réponses et outils, notamment hijackthis qui nous permettrait de savoir ce qui tourne sur ta machine...

Voici ce que m'affichait Hijackthis

C'est le virus Blaster ou une de ses variantes. Il faut que tu installes les mises à jour KB823980 et KB824146 de Microsoft. Et ensuite, un nettoyage antivirus en profondeur...

et maintenant j'ai ça:
