Hey, I had a trojan horse called Noob 4 on my system and my software cleaned it out. I hope... Anyway, post clean-up, I was digging thru all my logs and in the event log there are two warning messages I'm kinda concerned about. They are entered at the same time. Says:
10/28
Source: WinMgmt
Event ID: 63

WARNING: A provider, WMIProv, has been registered in WMI namespace, Root\WMI, to use the LocalSystem account. This account is
privileged and the provider may cause a
security violation if it does not correctly impersonate user requests.

The other entry was for HiPerfCooker...v1.
Same day, same time, same everything:

At the expense of sounding really stupid, what the heck is this??? What do I about it?
Microsoft's website was no help at all.

Stupid sounding error messages are hallmarks of hackers and crackers, etc.
A trojan? Are you sure you're rid of it?
Have you tried SWAT IT from www.lockdowncorp.com?

Hey! Yeah, actually Swat-It found the trojan to start with. It says it's all cleaned up now. I'm thinking something is wrong here cause something or someone keeps turning my freakin' firewall off. That's strange, don't you think? I don't ever turn that sucker off, but now, every few days I'll notice that my firewall didn't come on when I started up Windows. It's kinda worrying me. Nobody has physical access to this computer other than myself. I can't figure out why anyone would want to hack into my computer, though. I'm just a lil ole nobody in the whole scheme of things, you know?

Is there any way I can tell for sure if I've been hacked? Any way I can stop it from happening again? Other than disconnecting my modem, I don't know what to do!
