I’m not a fan of MSN Messenger, and I usually remove it from any computer I am working on.  To find out why have a look at IM Botnet Infects Thousands Of PCs or try an internet search for “msn messenger security”.

It’s also disconcerting that this non-essential program is virtually impossible to remove from your computer – delete the folder from C:Program Files and it just keeps coming back! – A good enough reason to get rid of it if you know how!
