Question
Ahkntfs.exe is a rare variety of spyware. To remove it, first turn off System Restore. The reason for this is that it probably hides a copy of the infection.
How to disable or enable System Restore in Windows ME:

How to disable or enable System Restore in Windows XP:
http://service1.symantec.com/SUPPORT/tsgeninfo.nsf/docid/2001111912274039?OpenDo...
Now open Task Manager (CTRL+ALT+DEL). Then click the processes tab, click on Ahkntfs.exe, then click End Process. Click Yes to confirm.
Next open a command prompt with Start --> Run, type command.com in the box and click OK. This will bring up a window where you can type commands. Type "del C:\WINNT\System32\?hkntfs.exe".
Your final task is to clean out the program from the Registry. Click Start --> Run and enter Regedit in the box, then hit OK. This brings up the Registry editing progam. The easy way to find it is to click Edit --> Find. This will bring up a box where you can enter "?hkntfs.exe". Now make certain the boxes labeled keys, values and data are all checked. Click "Find Next." Anything it finds, highlight it and delete it.
Now it is safe to reenable System Restore.
