Win 7 - Non si avvia explorer all'avvio

[Tecnomiky]

Ho win 7 ultimate e all'avvio l'explorer.exe non si avvia,
appena accedo mi appare una finestra dell' esplora risorse, non si vede ne la barra delle applicazioni ne desktop,come devo fare?
Per avviarlo devo aprire il task manager e fare avvia explorer.exe

[Eress]

Apri il prompt come amministratore e quindi digita il comando: sfc /scannow e dai invio aspetta che abbia terminato il ripristino quindi riavvia il pc.
Ti conviene anche fare delle scansioni AV

[Tecnomiky]

Ho provato a fare sfc /scannow ma non ha trovato nessun problema e ho già fatto la scansione con av
La versione di win 7 è ultimate

[Eress]

Prova una scansione con HiajsckThis e posta il log, vediamo se ci chiarisce le idee

Hai il pc infetto almeno da questo:

probabilmente un figlio di trojan se fossi in te passerei direttamente nella sezione apposita alla rimozione

Ho risolto tutto con una scansione con Malwarebytes' Anti-Malware

[Eress]

Rifai la scansione per sicurezza, comuqnue se davvero avessi risolto, come ho già scritto ieri in altra sezione del forum sono sempre più convinto che MalwareBytes in questo momento sia il miglior programma in circolazione per la rimozione del malware
