Salve a tutti.

Purtroppo il Trojan.Win32.Dialer.rm è riapparso, rilevato dal mio antivirus, e ho riapplicato la procedura di rimozione già segnalatami da Topdrake e da me usata in precedenza: il Removal Tool del LinkOptimizer-Gromozon-trojan Lop_AH (AVG)-trojan Agent (Avast) della Symantec.
Ecco il logfile di Hijackthis, dopo la procedura di rimozione (Spero che anche questa volta, Topdrake, tu sia così gentile e disponibile nel darmi una mano per estirpare definitivamente questo malware! ) :
