Ciao a tutti. Ho bisogno nuovamente del vostro aiuto, mi sono trovato improvvisamente senza antivirus, nel senso che quando cercavo di aprirlo visto che mancava l'icona sulla barra, non si apriva e consigliava una nuova installazione. Ho scaricato nuovamente avg e tentando l'installazione (riparazione) nuovamente errore. Ho provato allora a disinstallarlo e purtroppo ancora errore. La scritta è la seguente: Computer locale: installazione non riuscita
Installazione:
Errore: Intervento non riuscito per chiave del registro HKLM\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Windows: creazione della chiave di registro.... Error 0x80070005

Un aiutino?

Ciao.
Disistalla AVG con questo Tool:
http://www.grisoft.cz/filedir/util/avg_arm_sup_____.dir/avgremover.exe
Fai una pulizia con CCleaner.
Riavvia il pc.
Riprova a installarlo.

Ho eseguito tutto ma purtroppo ho sempre lo stesso errore.

Non so se l'ultima riga di hijack si riferisca al norton..percaso l'avevi installato?

se si, prova e reinstallarlo e rimuoverlo con l'apposito removal tool

grazie simo, non ho mai installato antivirus norton. Bentornato monsee, ora provo con i tuoi suggerimenti, grazie anche a te.

bye bye

Grazie comunque per essere intervenuto eccellentemente su avg, amico mio

Bentornato Monsee
