Ok, here's the facts. I downloaded Wyvernworks firewall. It sucks. I uninstalled it, but it left behind a file called AppToPort.dll that I can't seem to delete. Normally, I'd just leave it, but it's running itself something like 30 times over (according to HiJackThis) and sucking up all my resources. My CPU Usage is maxed at 100%. I've tried to delete it in safemode, tried the command regsvr32 -u AppToPort.dll to remove it, and tried using PView to kill it, but it simply comes back.
Using W2K Pro w/SP3 as the OS.

Any suggestions?

Hi,
You can try this options:
As you have mentioned that your OS is windows 2000 with SP3, try to remove it by going to registy using regedit
The path may be any of these 2 location
1) HKLM>Software>Microsoft>Windows>CurrentVersion>Run (or) RunOnce (or) RunOnceEx
2) HKCU>Software>Microsoft>Windows>CurrentVersion>Run (or) RunOnce
and remove the DLL.

If the above does not work, unhide all the files by going to folder options in explorer and then search for the file.
Then use PView to see the file, now go to the file location where the windows search found the file, here hit SHIFT+DELETE and do not hit ENTER, kill the process throug PVIEW and in the next immediate second hit ENTER.
This should work out.
Let me know if you need any help.

If you are still having problems, down Unlocker from http://tinyurl.com/dzy4d and give it a try.

Some stubborn files which are in use require killbox at http://www.killbox.net/.

And lastly, many files can only be deleted in Safe Mode (some only by slaving the drive in a good PC and deleting it there).

Dear friends:
In my case I had a problem with this file: “wvUmmjkh.dll” so I had to do these things to delete it at all.
1- Download the software “Unlocker” in this link:
http://www.download.com/Unlocker/3000-2248_4-10493998.html?tag=lst-1&cdlPid=10838644
2- Restart the computer in Safe Mode (when restart press F8).
3- Once the computer is ready again I went to the directory:
C:\windows\system32\wvUmmjkh.dll and “put the trash can very close” from the file to be deleted, I did it like this because the infected file was linked with the winlogon.exe and the explorer.exe and I had no option as fast as this.
4- Use the “Unlocker” software with the infected file and unlock all the files linked to the virus or spyware. In this moment you have to be very fast and throw the file into the trash basket, if you don’t make it fast, the computer is going to restart (in my case, because I was killing to important processes: winlogon.exe and explorer.exe) and you’ll miss the chance to make it in one simple try, I think that you have 2 or 3 seconds to do this action.
5- Once you finished deleting the file I had to download another program called “HijackThis”:
http://www.download.com/Trend-Micro-HijackThis/3000-8022_4-10227353.html?tag=lst-1&cdlPid=10781312
and began to make a “Do a system scan only” of the disk. When it finished you can see a list of all processes running in your machine, in my case the file “wvUmmjkh.dll” was with an indication of “missing file” so the only thing that I had to do to end all this was to delete the registry who belonged to it, very simply, just check the box and press “fix checked” and the registry will be inmediatly erased.
Just in case, with “HijackThis” you have an option of “Delete on Reboot”, in some cases it works and sometimes not.
My best regards, Milton Martorella.
