<img src=icon_smile.gif border=0 align=middle> Ciao Amici ! Posso chidervi se questa voce che ho trovato (con SpyBot) nell' esecuzione automatica è pericolosa e se posso eliminarla?
TkBellExe "C:\Programmi\File comuni\Real\Update_OB\realsched.exe" -osboot
Nel controllo automatico del Log è segnata come sicura ma da qualche parte ho letto che non lo è.
Mi controllate il Log ? Eccolo:

Nell'attesa vi saluto con tanti...<img src=icon_smile.gif border=0 align=middle><img src=icon_smile.gif border=0 align=middle><img src=icon_smile.gif border=0 align=middle> Ciao

Se per Tkbellexe ti riferisci a questo
<BLOCKQUOTE id=quote><font size=1 face="Sans Serif, Arial, Helvetica" id=quote>quote:<hr height=1 noshade id=quote> O4 - HKLM\..\Run: [TkBellExe] "C:\Programmi\File comuni\Real\Update_OB\realsched.exe" -osboot

si una parte del Real Player e quindi è meglio tenerlo se hai intenzione di continuare ad usare il programma senza problemi.

Se invece te lo trovi in

C:\Tkbellexe.exe

allora si tratterebbe del W32.Lovgate.AO@mm, ma non è il tuo caso.<hr height=1 noshade id=quote></BLOCKQUOTE id=quote></font id=quote><font face="Sans Serif, Arial, Helvetica" size=2 id=quote>

Questo è un brano (esauriente, mi pare) tratto da un altro forum e che chiarisce il tuo interrogativo.

<img src=icon_smile.gif border=0 align=middle>Anche questa volta Vi ringrazio con il cuore per l'aiuto che ci donate. Ciao!<img src=icon_smile.gif border=0 align=middle><img src=icon_smile.gif border=0 align=middle><img src=icon_smile.gif border=0 align=middle>
