p2pnetwork.exe - HELP!

Hi, my first post here, so hopefully I'll do this okay.

Due to my own stupidity, I managed to get 'p2pnetwork.exe' on my system. It wasn't picked up by my anti-virus software or my previous spyware programs, but I installed Microsoft Antispyware which picked it up, but I'm having trouble getting completely rid of it.

I've visited a few forums, and have followed the advice on some of those, which has cured a lot of the syptoms. I can now access the Task Manager via 'CTRL + ALT + DEL', but I cannot access 'Regedit' from the 'run' command, although finding it on the 'c:' drive and clicking the icon does allow me access. I've worked in safe mode and managed to remove a lot of the problem.

I still have one nagging file which keeps occuring, which is an instance of 'p2pnetwork.exe' which is picked up by Microsoft Antispyware. No matter how many times I try to remove the thing, it re-appears (even in safe mode). This is the only item Antispyware finds on my system, everything else is clear (previously tehre were 24 items which needed attention).

Could you please advise me further, my HijackThis log is below :
