Ciao Symon83,

fixa con hijackthis:

      > O16 - DPF: {1D4DB7D2-6EC9-47A3-BD87-1E41684E07BB} -

O2 - BHO: (no name) - {7E853D72-626A-48EC-A868-BA8D5E23E045} - (no file)....e scansiona con superantispyware "aggiornato".

flashutil10a.exe non risulta infetto, ma se vuoi analizzarlo, caricalo su virustotal.

Avg da qualche giorno da i numeri!!!

[symon83]

Sinceramente non so che cosa sia successo...ho riavviato e non mi fa più sto scherzo! Comunque dovesse ricapitare seguirò le tue indicazioni alla lettera! Grazie mille ciao ciao.

E' relativa a windows live e hijackthis non trova il file a cui fa riferimento, è un bug.;)

In effetti questa voce fa riferimento alla chiave di registro:

HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\Explorer\Browser Helper Objects

Giusta la nota di gio!
