Spero in un vs. aiuto
grazie

Se li ha disabilitati l'Amministratore, direi di domandar direttamente a lui di riabilitarli.

Quello che scrivi è vero, Bazz, come dimostra la voce:

O7 - HKCU\Software\Microsoft\Windows\CurrentVersion\Policies\System, DisableRegedit=1

che concerne proprio il Regedit e indica un'infezione in corso (e va, dunque, "fixata" quanto prima).

Altra voce da fixare (ma, questa volta, solo perché rappresenta un file ch'è "svaporato") è:

O2 - BHO: Internet Explorer Plugin - {91970793-C69B-414F-9DFF-7E0722955ABA} - polddfr0.dll (file missing)

Tuttavia, se non viene informato l'Amministratore e non si occupa lui della faccenda, come può fare un Utente con permessi limitati a intervenire?

"disabilitato dall'amministratore" è il messaggio che viene visualizzato alla richiesta di regedit, purtroppo l'amministratore e l'utente del mio pc sono sempre io, probabilmente non ero stato troppo chiaro prima, me ne scuso, grazie per le risposte, credo anch'io che ci sia un virus, la scansione di avast è pulita, non saprei come liberarmene, se qualcuno ha qualche suggerimento ...

Abbi pazienza, Pas: da quel che avevi scritto non ho capito che l'Admin del tuo computer eri comunque tu (pensavo ad un computer "dell'ufficio" nel quale tu non fossi "administrator")..
Se così stan le cose, ha ragionissima Bazz.
