virus trojan

[bugger]

il mio antivirus AVG F.E. mi ha segnalato la presenza di un virus Trojan Horse Generic 2ASQ in C/Prog/FileComuni/Services/IPZKqJ.exe.
i tentativi per sanare o mettere in quarantena sono negati in quanto "il file non è accessibile". ho provato anche con altri antivirus con lo stesso esito.
Cosa posso fare?? il report di HijackThis v1.99.1 è il seguente:

Ciao, hai il linkoptimizer purtroppo. Scarica questo tool:

http://www.prevx.com/gromozon.asp
disattiva l'antivirus, chiudi applicazioni e programmi, esegui il tool. Al riavvio del computer, il programma terminerà la scansione. Inserisci in un post il resoconto dello scan (dovrebbe trovarsi in C:\Gromozon_removal ).

[bugger]

ho eseguito quanto consigliato e penso che sia riuscito. il tool alla fine mi ha chiesto di installare il programma me lo consigli? nn confligge con altri già installati e x linkoptimizer nn c'è niente da fare?

cmq grazie mille x l'aiuto, di seguito il rapporto di gromozon_removal

Trojan.Gromozon Removed!

[Luke57]

Ciao, il tool dovrebbe aver rimosso il trojan.
Fai anche questa verifica:
apri hiajckthis, premi "open the misc tools section", "open unistall manager", fra le applicazioni se trovi linkoptimizer o connection services le evidenzi e premi "delete this entry".
