Win9x (and ME with third party s/w) machines can display "Messenger spam".
They seldom do though as it is very rare for the non-default, MS-supplied
(at least in Win9x) utility that listens for them and displays them to be
enabled, and the cases where it is enabled, the odds are very high the
machine will part of a relatively competitently run corporate or similar
LAN which will, by definition, block "Messenger spam" at a perimeter
firewall or through some other mechanism before it can get to the PC.

Get the name of the task and search the registry for it. Note the
filename(s) from the registry entries referring to the task name (this
does not necessarily always work!), eliminate any "coincidental"
references. Nowadays a lot of malware re-uses legitimate service names
to confuse naive users -- make sure that you know the thing you are
looking at is not a legitimate OS service component before proceeding.
If you are sure you have located the filename of the offending service,
restart the machine in DOS mode, change to the directory where the
file(s) of concern are and rename them (for example, .EXE to .EX_, .SCR
to .SC_, etc). Try restarting Windows normally...
Are any start-up errors reported? Does the machine seem to be "back to
normal"?
If all seems right (or even if it doesn't but you cannot resolve it
further yourself) zip (or similar) the suspect file(s) you found and
send them to your preferred antivirus developer(s) for analysis and so
they can add detection of this to their next update.
If you need any more help, you are welcome to Email me directly at this
