Ciao Wolf Otakar,
ho provato ad effettuare una scansione con Virit in modalità provvisoria e non mi ha trovato niente..

...Effettivamente andando a guardare in system32 spoolw.exe e igfxsvc.exe non ci sono più... sono spartiti!!

..Resta comunque purtroppo il fatto che explorer.exe e iexplore.exe non si avviano..

Ah, se può aiutarci questo è quello che HijackThis ci dice...

Ottime notizie Wolf Ottakar:

Logfile of The Avenger version 1, by Swandog46

Finished! Terminate.

Da questo deduco che lo Script che mi hai dato non ha superfunzionato... **
TUTTAVIA** sorgono ora due problemi molto più enormi quali: explorer.exe e iexplore.exe che non funzionano più, nè si avviano all'avvio nè in alcun modo riesco a farli partire..

Cito all'apertura tramite task:"Impossibile trovare il file "iexplore.exe". Verificare che il percorso e il nome del file siano corretti e ritentare. Per cercare un file fare clic sul pulsante Start, quindi scegliere Trova."

(Sto usando Firefox e lo ho aperto da Task Manager)

..Diciamo che posso comunque aprire i programmi che mi hai fatto scaricare in precedenza e tutti gli altri ad eccezione dei 2 sopracitati che sono però i fondamentali... Aka, sono rovinato... Che faccio?!!!

Ecco quanto...
