Questa nell'analisi automatica me la dà da eliminare, ma aspetta un esperto (che io non sono) ed intanto effettua le scansioni con il tuo antivirus: O4 - HKLM\..\Run: [Monitor] C:\WINDOWS\PixArt\PAC207\Monitor.exe

Che client di posta usi? Se Outlook Express prova a verificare in strumenti, opzioni, connessione di non avere il flag su 'disconnetti dopo invio e ricezione'.

Purtroppo quella voce O4 - HKLM\..\Run: [Monitor] C:\WINDOWS\PixArt\PAC207\Monitor.exe è solo una parte del problema.
Anche questa C:\PROGRA~1\SPYWAR~1\sp_rsser.exe correlata a Spyware Terminator è (per me ) da eliminare.
Per non parlare di questa C:\WINDOWS\PixArt\PAC207\Monitor.exe che (per me è collegata alla prima)
e c'è pure dell'altro.

Un consiglio: aspetta P2 è bravo.
