Titolo: kaboom.dll....cos'é?

Ciao, ho un comp. con windows 2000 SP4 e lanciando HijackThis ho trovato due
voci che non so classificare.
O4 - HKLM\..\Run: [IEAgent update check] C:\WINNT\system32\iewatch.exe
O23 - Service: InstallDriver Table Manager - Macrovision Corporation -
C:\Program Files\Common Files\InstallShield\Driver\11\Intel 32\IDriverT.exe
Ma soprattutto questa:
O2 - BHO: IE Agent - {CC56A1F3-9B83-45FF-8CB6-D58959492F0F} -
C:\WINNT\system32\kaboom.dll
Ho prpvato anche a entrate in Safe Mode e rinominarlo in kaboom.bak, ma al
riavvio sucessivo il sistema ha ricreato un kaboom.dll con la stessa data di
quello vecchio.
Qualcuno sa dirmi se è il caso di intervenire?
Con Spyboot e AVG Free non ho trovato nulla, e nemmeno con la scansione
online trovata qui:

Grazie a tuti e ciao
P.S.
Se può essere utile posto il log di HijackThis
