Virus che invia mail

[Tarrion]

salve a tutti, volevo esporvi la seguente questione: mi sono accorto che poco dopo aver connesso internet avast mail scanner inizia a scansionare mail su mail in uscita come se ci fosse un virus chele crea e le invia tramite la mia connessione, ma non riesco a trovare il processo in task manager, posto un log di hijackthis fatto adesso mentre naturalmente le mail vengono inviate a raffica...

[wizard1993]

cambia antivirus e metti active virus shield (clikka)

aggiornalo e fai una scansione (nella guida linkata c'è tutto) poi scaricati un firewall e installatelo; poi posta un log di hijackthis

[pcì]

sbaglio o sei senza firewall?
sostituisci avast con un antivirus migliore (avira, kasperky, avs), fai scansioni con asquared free, superantispyware, avgantispy, bitdefender-online...

insomma le solite cose

edit: preceduto da wizard

[Tarrion]

grazie del consiglio, ma ho bisogno di levare questo virus immediatamente, poi provvederò a cambiare antivirus, potete dirmi come fare?

dopo aver fatto questo modifica da regedit la chiave

in maniera da renderla come la seguente

"%System%\userinit.exe",

ovviamente post il log restituito da avenger
