It is just that your signature stated you have MBAM free, which as far as I'm aware doesn't have the mbamswissarmy.sys driver resident.
Again even my win7 system with MBAM Pro doesn't detect mbamswissarmy.sys in the anti-rootkit scan 8 minutes after boot or in the behavior shield. So I don't know if this is an issue only seen in win XP (and I don't use the MBAM Pro version in XP.
I only have MBAMService.exe and MBAMgui.exe running in XP and win7, I can't see anything of mbamswissarmy.sys, even when I look in services.msc, and check the dependencies, shows only MBAMProtector.
The links to the other topics are unrelated as they aren't about your problem with mbamswissarmy.sys.
I have just started off a custom full rootkit scan, so I will let you know the outcome when complete.
