[demarrage] probleme de ralentissement

Bonjour je m'excuse de vous deranger mais j'ai un preobleme assez derangeant au demarrage.
Mon pc est très ralenti et en regardant le gestionnaire des taches je vois que "MSKsrvr.exe" prend toute la place.
Je ne comprend pas car jusqu'a present tout allait bien, je pense que c'est lié à McAfee installé recement mais je ne suis pas sur.

Voici au cas où le rapport HijackThis
