"client services for netware"

Tried the AO search engine and skimmed for previous posts--also checked Google. I committed a "cardinal sin"and allowed someone to use my computer while away and they loaded netmeeting and it "took over". I've tried deleting every way I know how and nothing(so far) has worked. I also went to add/remove...not listed. Running win.xp pro. Newbie-and a green one at that. If you must "beat me up"...please apply pressure to the wounds and bandage b-4 leaving me in the gutter to "die". Thanks--help greatly appreciated.
