Non hai detto che problemi hai, forse il pc un pò rallentato ?
Il log è pulito, elimina le toolbar di Skype e di Avast inutili, tieni solo quella di Google.
Controlla le voci 016 se conosci tutti quei siti, se qualcuno non lo conosci elimina la voce.
Ciao

Conosci questi programmi:

C:\PROGRA~1\COMMON~1\X10\Common\x10nets.exe
C:\Apps\Softex\OmniPass\OPXPApp.exe
Se non li usi eliminali.
Attenzione a Real Player, molto pesante per il sistema.
Hai abbastanza RAM installata ? minimo 1 Gb.
Fai un controllo con QUESTO sw, lo apri e clicca su Avvia
lascia fare fino a quando ha terminato, ti chiede il riavvio acconsenti, non rilascia nessun report, questo programma serve a correggere diversi errori di XP, quando ci sono.

Installa QUESTO lo devi aggiornare e poi fai una scansione COMPLETA non rapida, elimina tuto quello che troca.

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.

Ti informo, se non ne sei a conoscenza, che tutte le voci 04 non rimuovono nessun programma ma disattivano solo l'avvio automatico, accelerando l'apertura del S.O.

Alla fine fai una pulizia con Ccleaner compreso il Registro, per il registro spunta tutte le voci.

Poi vai in C:\windows cerca la cartella prefetch, aprila ed elimina tutto il contenuto, non eliminare la cartella.

Disattiva il ripristino configurazione di sistema
start,pannello di controllo,sistema,configurazione di sistema,metti la spunta a
"disattiva ripristino configurazione di sistema su tutte le unita'",applica,ok.
spegni e riaccendi il pc, (fai l’operazione inversa per riattivarlo) e crea un nuovo punto tuo.

Per creare un nuovo punto di ripristino del sistema in XP

Start - Tutti i programmi – Accessori - Utilità di sistema - Ripristino configurazione clic su Crea
nuovo punto – Avanti mettere un nome del nuovo punto poi clic su crea ok, chiudi.

Fai sapere se ci sono migliorie. Ciao
