svchost con utilizzo di ram altissimo

[megasuper2]

questo accade anche quando internet non è funzionante sapreste indicarmi se è normale?

Aggiornamenti di windows in corso?
Quando mi scarica gli aggiornamenti svchost passa regolarmente i 100 mb per parecchi minuti.

Ogni quanto ti succede?

purtroppo è perenne

Cominciamo a vedere un log della scansione di hijackthis e magari controlla, se hai un firewall, chi è che genera tutta questa attività.

non penso ci sia un virus

[crazy.cat]

Guarda con process explorer cosa gira dietro a quel svchost, quali altri processi sono collegati a lui.

[megasuper2]

intanto grazie sembra essere questo il colpevole:
C:\Windows\System32\audiodg.exe

[crazy.cat]

Guarda se può essere utile http://www.tuttotech.com/archives/8040/ ... udiodg-exe

[megasuper2]

pare non sia mutato nulla eventualmente se lo terminassi dal task manager la rete funzionerebbe comunque?

[megasuper2]

provato anche a terminarlo ma dopo poco si ripresenta

[Berga95]

pare non sia mutato nulla

Dopo la modifica hai riavviato il pc? Non si sa mai

[megasuper2]

ehm no
comunque dopo averlo terminato svariate volte sembra non essere ricomparso
un ultima informazione svchost non ha a che vedere con la rete perché alcune applicazioni come nel mio caso il gestore audio dovrebbe connettersi e non potrebbe usare un proprio nome invece di svchost?
