[lalalallala_la]

da quando mi è comparsa la finestra di un finto antivirus, nonostante abbia sempre provato a chiuderlo si è autoinstallato, faccio fatica a navigare, e avast mi segnala che firefox cerca di infettare vari file nel mio sistema, ogni minuto circa 15 file con WIN32:Ramnit-G, VBS:Exe-Dropper-Gen[trj], NSIS:Sefnit-C[drp], WIN32:Rootkit-Gen[rtk]
non riesco a fermarlo, aiutooo! grazie mille

Ciao.

Assicurati di avere accesso a file e cartelle nascosti
(Pannello di controllo-> Opzioni Cartella-> Visualizzazione)
1) Metti la spunta su: Visualizza file e cartelle nascoste.
2) Togli la spunta: nascondi file protetti di sistema (consigliato)

Avvia hijackthis, metti la spunta alle voci che andrò ad elencarti e con tutte le applicazioni chiuse e disconnesso da Internet,premi su "fix checked":

Scusate, sono stato via un po' .
Comunque, ricapitolando, non riuscivo quasi a far niente sul mio computer, si bloccava tutto in continuazione, adesso ho fatto quello che mi hai detto e sembra che vada meglio.
Ma quando apro firefox mi da gli stessi problemi, ho reinstallato firefox, ma il problema non si risolve. Ovvero, si creano tanti processi firefox.exe e rubano tutte le risorse di sistema, l'antivirus mi segnala che firefox.exe o altri programmi che sto usando stanno cercando di infettare vari file nel mio sistema.

qui i logs di SAS e MBAM:

aspetto consigli grazie mille

Ciao.
Guarda che devi aggiornare Malwarebytes.

[lalalallala_la]

ecco fatto!

mbam-log-2011-05-02 (12-56-44).txt

ho riaperto firefox, e adesso sembra che tutto sia tornato a posto.
grazie mille!
