scusa, aggiungo velocemente che sto svuotando il contenuto della cartella Temp, ma non mi fa buttare via un file che si chiama IadHide5.dll. (guardando meglio, è lì dal 2004 quindi forse non è cattivo...)
Vado avanti col resto

buongiorno! eccomi
ho fatto tutto. Posto un altro log?

ok! eccolo:

Non è per rompere le scatole......
Ma eliminando quel file della Sony, potrebbe avere problemi, di trasferimento di file multimediali.

avevo un programma sony di un lettore mp3, installato un anno fa per conto di un'altra persona - l'ho rimosso. Facendo la ricerca, ho comunque una cartella sony in E:/programmi.
procedo col resto o faccio altro?

ci ho provato, ma proprio quel file (content transfer wmdetector) non ne vuole sapere di essere eliminato

In Modalità Provvisoria dovrebbe lasciarsi eliminare.
Se non dovessi riuscire, diccelo... che faccian fuori la cartella incriminata in altro modo.

Elimina quelle che vedi.
Le altre, dovrebbero essere visibili in Modalità normale.

A me sembra pulito, il tuo ultimo LOG...
Aspetta, in ogni caso, qualcuno più abile di me per averne conferma.
Soltanto una cosuccia, se posso: vedo che uso XP Service Pack 2... Suggerirei, per avere un Sistema più difeso e performante, di installare il Service Pack 3 (il quale, d'altra parte) è caricabile anche a partir da Aiutamici.
A parte il fatto -ovviamente- che non mi par di aver notato, sul Sistema tuo, alcun valido firewall...

Grazie, Busto!
