Facendo una scansione con A-SQUARED mi risulta che il file di sistema CSRSS.EXE è infetto di BACKDOOR WIN32 BIFROSE.EM, il mio antivirus AVG non lo rileva ed anche facendo una scansione on-line con PANDA antivirus non viene rilevato questo virus.
Cosa devo fare? a chi devo credere ?
posto il mio HIJACTHIS e grazie a tutti
