write-protected spyware?

I am on a computer right now that has spyware/malware or something on it. When I open internet explorer, it automatically goes to a page I don't want it to, and if I type in one site, it'll go to another.
I've turned off system restore; cleaned out cookies and temps; ran Nortons, Ad-aware (in normal and safe), Spybot (normal/safe), and everything else I'm suppose to; ran hijack-this (4 times), and physically gone (in safe mode) and tried to delete these .dll files. But one of them is Write-protected and I can't delete it! The rest just keep coming back. They are in the system32 folder.
These are the 3 that wont delete (I deleted about 10 others)

w8c654~1.dll.dll.dll.dll.dll.dll.dll.dll.dll.dll.dll.dll.dll.dll
2cid1n16yewonthd.exe
3dfgrpcthe2j2711.dll.dll.dll.dll.dll.dll.dll.dll.dll.dll.dll.dll (this is the one that is write-protected).

They all say the company is Melkosoft.

Oh ya, when I ran hijack this there was a o2: BHO that I would delete...then run hijack again..and it would be back.

did. Adaware and Spybot didn't pick any of those three mentioned above; I could not get to the sites for Bitdefender, RavAntivirus, TonyK's list and Pacmans startup list (instead this page with an address ending in .dll shows), and I don't remember what the other programs resulted in (I'm not at that computer now)...so I guess I can't post the other results until tomorrow
