I've removed MTX from twenty computers without any problem. This computer is a problem.

It's a Win98 (first edition) machine.

YES, I obtained the latest virus definitions (even though the MTX fix was made back in August)

I've installed InoculateIT and Norton's from safe mode, and have run F-Prot from a Win98 StartUp Disk. I've also replaced the explorer.exe, regedit.exe, taskman.exe, wsock32.dll from a Startup Disk boot, then booted to Safe Mode to manually delete the HKey_Local_Machine\Software\[Matrix] subkey and the mtX.exe value at Key_Local_Machine\Software\Microsoft\Windows\Curre ntVersion\Run

I've also run the <a href="http://www.sarc.com/avcenter/venc/data/w95.mtx.fix.tool.html">SARC MTX fix tool</a>. It doesn't find the virus if I run it after NAV or Inoculate-IT, but will if I boot to Windows after running F-Prot.

The antivirus programs are set to check every file.

Chkdsk finds 655,360 total bytes memory so it's probably not memory resident.

I think I could scan for viruses in Safe Mode, reboot to Safe Mode, and still not find any viruses.

Disableing all the startup files via msconfig or the load= files in te system.ini doesn't do anything.

Any ideas?
