Thanks UK Bob.

Bitstream-surfie,
All seems fine on my computer, but I am still to reinstall LimeWire. I just haven't had time with exams at the moment. You can see of how this was starting to worry me.
With MediaAccess.exe and MediaAcck.exe I wasn't able to kill either of them through task manager. Every time I did they immediately reopened themselves.
I just remembered that I used a program called Startup Control Panel (CPL) that integrates with Windows Control Panel. It shows everything that appears in HKLM/Run, HKCU/Run, Services and Startup. Within I found p2pnetworking.exe but it too kept reappearing everytime I booted the PC.
If CPL might work for you grab it at Mike Lin's Home Page
It probably would've been a good idea to state that I too am running XP Pro somewhere before lol.
