Help! I've cleaned numerous things off of my Win 2K PC. The only thing remaining is a pesky file known as nztrap.dll. I've tried Killbox, ewido Security suite, HijackThis, and all can not remove this file. Ewido sees the file as part of the Look2Me virus. Symantec NAV doesn't fix it, neither does their removal tool.

I haven't been able to find anything on the web about this file. Here's my HijackThis log file.

Thank you for the quick reponse. I was able to rename the nztrap.dll to nztrap.lld, and then created a fake one using notepad to take its place. I did this in the Win 2K recovery console. The recovery console gives me greater access to files than safe or normal mode does. I have access to two PC's right now. The problem one is doscinnected from the Internet for obvious reasons.

Here's the log. I can see many things that don't look right.

Actually, I was able to get that stuff out of my system. It's completely clean. When I used the Recovery Console for Win 2K, I was able to rename the NZTRAP.DLL to NZTRAP.LLD, and then created a fake NZTRAP.DLL using notepad to take its place.

Then I ran ewido again and I was able to clean the bad DLL's since the NZTRAP.DLL was no longer in memory. It also cleaned a few other things. Just to make sure, I ran HiJackThis and it looked good. I also ran RegCleaner to delete any other problems. I also ran AdAware one more time as well. And, I ran Cleanup and finished the job. There was several reboots to test the system between scans.

This was a tough one. Since the NZTRAP.DLL goes right into memory upon boot in either safe or normal mode, the only thing that saved me was the Win 2K Recovery Console boot option.

I'm sure your addtional help would have helped me also. I'm just glad that I have been using PC"s since the original IBM PC. A little caution goes a long way.

Thanks for the help.
