good advice, thanks but just lastly what do you mean by "update update update"?   I thought McAfee does this all the time, as its constantly telling me that everything is up to date and fine. My subs are always renewed every October

McAfee is just an Anti virus program so it can only find and remove viruses.. Tune up Utilities helps clean up your PC from other things that happen when you uninstall programs etc.. Always have an anti virus software .. 

Not all AV software will get rid of those Bearshare things, they are designed to be hard to get rid of and as cat says they won't be detected by AV software. I speak from experience because I have managed to get quite a few of these little nasties in the past couple of years
