come eliminare i virulenti intrusi

[Biancaluna]

Salve a tutti, ragazzi!
Purtroppo dopo anni di immunità, qualche fastidioso virus si è venuto ad insediare nel mio pc. Ho provato ad eliminarli con Avast e con Avira, qualcuno è stato terminato, ma altri sono rimasti. Il guaio è che non so come identificarli, ho utilizzato HijackThis con il seguente risultato:

Qualcuno di voi potrebbe aiutarmi ad identificare ed eliminare definitivamente questi fastidiosissimi parassiti?

Vi ringrazio in anticipo

il fatto che sia il tuo 1° post su questo forum o che tu sia (legittimamente) allarmata per la salute del tuo Pc non ti esime dal dover rispettare le regole di sezione, in particolare
Guida alla disinfezione per Infetti.

Cmq si', sul tuo Pc sono visibili diverse putt**, ad es:

	C:\DOCUME~1\Vero\IMPOST~1\Temp\Egr.exe
	O4 - HKCU\..\Run: [HJRUDZ5DT2] C:\DOCUME~1\Vero\IMPOST~1\Temp\Egr.exe
	O4 - HKLM\..\Policies\Explorer\Run: [COM Service] C:\WINDOWS\msagent\msctxi.com
	O20 - AppInit_DLLs: ,C:\DOCUME~1\Vero\IMPOST~1\Temp\173xxx.dll

Devi usare una combinazione di programmi indicati nelle regole di sez. che ti ho riportato poc'anzi, in particolare (e per fare prima..) utilizzerei HitmanPro + Malwarebyte, ciao
