Exit from systray ?

And the stop doesn't unload it from memory.

Ok, but does the process continue to use CPU in this situation?
Seems like a driver that was not unload from memory, nothing more. Maybe I'm wrong

I think having win98 doesn't help there is no easy way to kill a process (especially as it isn't displayed), as Igor said the resident processes aren't disabled (I assume they aren't unloaded just don't scan) so it makes it easier to resume/start again.

I've just noticed that Stom is 'Using Win98SE, Avast 4.6.665' I doubt that it would resolve this but Stom should update to 'Avast 4.6.691.

ProcessExplorer from www.sysinternals.com will do it even for Windows 98.
Only does not scan? I'm really surprised...

Good eyes as ever 
Thanks David.
