Analyse suite à réinstallation

Ton XP est en SP2

Il y a une mise à jour de sécurité globale SP3. Il faudrait que tu l'installes
Tu peux le trouver ici

https://www.clubic.com/telecharger-fiche242026-windows-xp-service-pack-3.html

Ensuite mises à jour du SP3

Et reviens ici après, un p'tit truc me chiffonne.

Spy bot plus très utile.

Re bonjour depuis LA REUNION où le temps est très beau

J'ai installé SP2 et remis avast (et norton livré avec la restauration usine de lenovo).
Je trouve qu'il rame un peu au démarrage ???

Rien de spécial dans ton rapport sauf que tu as plusieurs antivirus, certainement la source de ton ramage sans compter d'éventuels conflits.

Symantec®Norton Internet Security
Alwil Avast! Antivirus
Symantec®Norton LiveUpdate Ghost/Antivirus/NIS
Symantec®Norton SystemWorks
Safer Net Working®Spybot S&D
Lenovo Client Security Solution
ALWIL Software avast! Antivirus
Symantec®Security Technologies
Symantec®Norton LiveUpdate

Il y en a que tu as payé la-dedans ou ce sont des versions gratuites ?

Je n'ai rien payé ou plutôt Norton était installé lors de l'achat de ce Lenovo mais seulement 3 mois d'essai gratos. Je suis passé ensuite à avast. Lors de la restauration de ma machine hier au format "sortie usine" j'ai retrouvé ce norton pour 3 mois ...

Le "Lenovo Client Security Solution" est le système de sécurité interne à lenovo IBM ( entreposage et récupération de mots de passe, lecture empruntes digitales ... mais rien à voir avec protection anti virus

Safer Net Working®Spybot S&D : je ne connais pas et ne sais pas d'où ça vient

Tu ne dois avoir qu'un seul Antivirus sur ta machine

A toi de choisir entre Norton et Avast (Spybot n'est pas un antivirus mais un anti malwares tu peux le garder)

Pour désinstaller proprement Avast
Pour désinstaller proprement Norton
