LANGSOM SHUT-DOWN på WinXP Pro (HijackThis log vedlagt)

Hej,
Min PC er enormt langsom (ca. 2 min.) ved shut-down. Den er derimod enormt hurtig ved start-up (ca. 15 sec.) Jeg kører WinXP Pro SP1, 2,8GHz, 512MB DDR400 Ram, så maskinen skulle være ok. Spørgsmålet er altså: Hvorfor er min PC så langsom ved shut-down ???
Håber nogen derude kan hjælpe.
Har vedlagt log fra HijackThis ver. 1.98.2 (hvorfor skriver den så ver. 1.97.7 ?)
Nå her er loggen så:
