Dopo una scansione con VirIT sono stati trovati dei trojan sul pc.
Sono stati eliminati tutti tranne che csrs.exe e csrs.dll perchè risulta impossibile eliminarli anche a mano o anche solo spostarli di cartella.
Ho bloccato il file con COMODO Firewall perchè si lanciava ogni 10 secondi.
Se qualche anima pia può aiutarmi gliene sarei grato.
Posto il log di HijackThis se può servire:

Grazie a tutti anticipatamente.

Ciao rambler.tonino,

Il log di hijackthis non evidenzia cose strane.
Dovresti postare il log di virit, collegarti a Kaspersky on-line scanner e fare la scansione estesa, come indicato qui.
Salva il risultato della scansione in un file, carica il file su http://www.freefilehosting.net e posta qui il link che ti viene assegnato.

PS: se vuoi, puoi presentarti qui

[rambler.tonino]

Ho scaricato Active Virus Shield (ha il motore di Kaspersky giusto?), l'ho aggiornato ed ho fatto una scansione...
24 file infetti ed eliminati tra i quali anche csrs.exe e csrss.dll!
Per avast e virIt non c'erano virus!
Sapevo che gli antivirus basati su kaspersky fossero migliori ma non immaginavo ci fosse tutta questa differenza...
Ora pare sia tornato tutto alla normalità.
Un grazie a bdoriano per l'aiuto.
