Ciao r16,
ieri Avira - mentre navigavo su siti normalissimi e consueti - mi ha segnalato d'improvviso che negava l'accesso a un virus (di cui non ho preso nota).
Poco dopo, w.defender mi ha chiesto di autorizzare "sdra64".
Guardando in rete ho visto che si trattava di un trojan, ho rintracciato un tuo recente post dove insegnavi a toglierlo dalla chiave di registro e mi sono arrischiato a farlo.
Nel dubbio, ho aggiornato e lanciato malwarebytes, che me lo ha rintracciato di nuovo e messo in quarantena.

Oggi pomeriggio negli account limitati non apparivano più le icone e la barra delle applicazioni e allora - in modalità provvisoria e dopo aver disattivato il ripristino - ho lanciato le scansioni di malwarebytes, poi spybot e poi avira.

Non mi hanno rilevato nulla e adesso anche gli account sembrano funzionare normalmente.

Per scrupolo ho installato ora Hijack This e ti allegherei il log per un tuo parere.
Grazie anticipate.

Ciao magomagu .
Preferirei, che quando si trova qualche problema,non si prendesse spunto da altri topic.
Ogni infezione, ha una storia tutta sua, e non è detto che, (anche se simile) bisogna usare le stesse procedure.
Specialmente, se si ricorre a delle eliminazioni, o modifiche del registro.
Non prenderla male, solo una maggiore attenzione, quando non si sà con precisione, cosa si elimina.


Avvia hijackthis, metti la spunta alle voci che andrò ad elencarti e con tutte le applicazioni chiuse e disconnesso da Internet,premi su fix checked

Dai una pulita (registro compreso)con CCleaner http://www.aiutaamici.com/software?ID=11223
Nella schermata iniziale di CCleaner, clicca su Opzioni e poi Avanzate, togli il segno di spunta a: Cancella i file in Windows Temp solo se più vecchi di 48 ore

Da Installazione Applicazioni, disinstalla le versioni installate di Abobe Reader, Adobe Flash Player (comprese quelle marcate Macromedia) e Javasun ( (tutte le versioni eventuamente presenti) .

Dopo la disinstallazione,dai una pulita (registro compreso)con CCleaner, e installa le versioni aggiornate di:

Se in fase di installazione, ti venisse rchiesta l'installazione di qualche Toolbar, non la installare.

Posta un nuovo log di HJT.

Ciao.
Fai cosi:
prova in modalità normale.
Se vedi che alcune voci non si cancellano, allora prova in Provvisoria.

Ho messo nel cestino le vecchie cartelle di java e così facendo si è installato tutto.
(Ho visto che lo stesso problema era capitato a Giza e ho fatto come lui, spero non mi sgriderai di nuovo).

Ecco il nuovo log, grazie di tutto e buonanotte.

Strano, avevo controllato accuratamente.
Però subito dopo la cancellazione, mi erano sparite le icone sulla barra delle applicazioni e ho dovuto riavviare. E' la prima volta che uso questo programma, probabilmente ho commesso qualche errore involontario.
Cosa che non sarà certamente successa ora, con questo log che ho scrupolosamente controllato.
Scusami per l'inconveniente e a presto.

Ciao r16.
Ho eseguito alla lettera.
Tutti gli account funzionano regolarmente. Le icone e la barra si vedono normalmente. XP viaggia spedito con gli standard consueti.
Grazie.
Buon fine settimana.
