Salve.... mi sposto su questa sezione per sottoporvi un problema giè accennato su tread di XP ma non risolto:
Aggiornamenti automatici che si scaricano ma non si installano; sono ste fatte prove, pulizie (Glary utilities, spybot e anche ccleaner, antivirus Nod 32, pcstress) nulla.... il messaggio è "errore nella cartella .tmp" - mai la stessa - e i 2 aggiornamenti critici sono KB974417 e KB951847 oltre ad un aggiorn di Microsoft.net Framework 1.1 s.p. 1
Mi suggeriscono di postare il log e vi chiedo aiuto. Oltre all'odiosa insistenza, la mancata installazione mi ha creato problemi con l'antivirus. Spero di riuscire a risolvere. Grazie.

il log non sembra abbia infezioni ma non riesco a vedere antivirus, quale usi? Vediamo se qualche amico esperto riesce a trovare qualcosa che mi e' sfuggito.

Comincia con aggiornare anche Hijack This : (disistalla prima la vecchia versione)
http://www.aiutamici.com/software?ID=11175
Poi:
Scarica ed installa MalwareBytes:
clicca qui per il download : http://www.aiutamici.com/software?id=80346
Prima di fare la scansione AGGIORNALO. (è molto importante)
Esegui una scansione completa del sistema.
Posta il log.

Per l'antivirus, ti consiglio questo:
Scarica Avira:
http://www.aiutamici.com/software?ID=10908

Lo configuri esattamente come in questa guida, in formato PDF:

http://www.zeusnews.it/zz_upload/PSV/Guida%20completa%20di%20%20AVIRA%20Antivir%209.pdf

Le voci indicate nella prima immagine a pagina 11 della Guida, spuntale tutte (nell'immagine non lo sono).
