The computer (Win98SE) is misbehaving, a couple of applications are not running correctly. After some checking and detective work, there seems to be an unknown application Otmaker running, ctrl+alt+del, stops it but then a new application thnal5c starts up. Checking in the temp directory, there are indications this application was installed yesterday by some unknown process. There are also related files installed in Windows/Systm. Removed the files and the system is behaving ok again.

Searched the internet for Otmaker - but other than a post in a forum dated this week, there are no traces of it.
