Vista lentissimo (soprattutto all'avvio)

[masito]

Posto il LOG di hijackthis, qualche consiglio?
Premetto che le scansioni antivirus e antyspyware non hanno segnalato problemi particolari

Avg se non ricordo male ha già un suo modulo antispyware, tenere attivo windows defender è piuttosto inutile.
O4 - HKLM\..\Run: [Windows Defender] %ProgramFiles%\Windows Defender\MSASCui.exe -hide

Questi sono una serie di processi a cui si può anche rinunciare senza grossi rimpianti, forse solo hpqSRMon.exe è di una qualche utilità se colleghi spesso periferiche usb. Potresti provare a disabilitarli e vedere se cambia qualcosa.

O4 - HKLM\..\Run: [RtHDVCpl] RtHDVCpl.exe

Questi sono altri processi eliminabili.

Puoi fare tutto da msconfig basta togliere i flag dalle caselline e poi riavviare. Solo windows defender devi poi anche disabilitare il servizio se non ricordo male.

Il log è pulito.
Mai provato ad usare CCleaner?

[sondlive07]

a me e successo dopo aver ripristinato il pc,
ma ho risolto deframmentando il tutto
se hai del tempo prova a farlo
