help removing MSN & associated components please

I accidentally installed part of MSN when installing 98 on
new pc and wish to remove it & all associated components as
I don't need it and it obviously leads to vulnerabilities
on system. Unfortunately, I've been away from pc's for 2yrs
(not in jail - 4x4 ing!) I also get a missing msnp32.dll
message on startup following 3 messages relating to missing
..vxd files ( .vxd msgs appear in 'dos'? before win
startscreen).
If anyone could help I would appreciate it.
Thankyou,
