Probleme avec mon anti virus

bonjour,
je me permets de vous ecrire car mon anti virus (norton) ne veut plus s'activer(auto protect), il me met erreur devant ainsi que pour la verification des mails.
G fait de multiples scan et ils semblent que des virus se sont propagé dans mon ordi.
J'aimerai eliminé ces virus et savoir ce que je dois faire pour que mon norton remarche normalement .
Avec tout mes remerciements,
Voici le rapport recu par manda :
