Scusate il disturbo, ma vista si è rallentato in avvio, gli antivirus non hanno trovato nulla. Mi date un occhiata al log di hijack this???

Il log è pulito, non sempre i rallentamenti sono dovuti a infezioni, nel tuo caso hai un sacco di programmi inutili e troppe voci in avvio, ben 33, quando ne bastano 4 o 5.
Le varie case che producono pc, da sony a HP ecc. hanno la cattiva abitudine di allegare un sacco di utility che di
utile hanno ben poco, creano solo rallentamenti e conflitti.
Prima cosa eliminerei tutti i programmi della sony e poi toglierei parecchie voci in avvio.
Se sei d'accordo ti posso dire cosa fare e cosa eliminare.
Fammi sapere. Ciao

Segui il percorso ed elimina questi sw:
C:\Program Files\Sony\VAIO Power Management\SPMgr.exe
C:\Program Files\Sony\VAIO Mode Switch\VMSwitch.exe
C:\Program Files\Sony\Network Utility\LANUtil.exe
C:\Program Files\Sony\Marketing Tools\MarketingTools.exe
C:\Program Files\Sony\ISB Utility\ISBMgr.exe
C:\Program Files\Sony\VAIO Update 5\VAIOUpdt.exe
Si tratta sicuramente di programmi che hai su un CD della sony, se qualcuno ti è indispensabile lo puoi sempre installare.

Chiudi tutti i programmi e disconnesso lanci HJT e clicca sul secondo pulsante: Do a system scan only poi metti la spunta alle voci che ti indico e alla fine clic su Fix checked.
