Its a virus, simple as that.
It also prevents you running Taskmgr.exe (Task manager) or regedit.exe (Registy editor)
Fisrtly in search your computer for msmovies.exe and delete it.
Then search for regedit.exe and run it.
Within regedit, highlight My Computer and click Edit/Find msmovies.exe It'll probably be in the C:\WINDOWS\Prefetch folder
Delete any entries which make reference to this file msmovies.exe
I have heard of a user who has had a similar problem with another file called winupdates.exe which again was a virus sitting in the memory designed to keep re-loading Limewire.
No doubt there will be more and with different names now, sooner or later.
The easiest way is to open task manager and if your computer wont run it search for taskmgr.exe, run it and try removing one task at a time, then close Limewire and give it 30 seconds to see if it re-loads before removing another task. This way you will identify the name of the offending program. Then look for this offending program in C:\WINDOWS\Prefetch and other locations if it is not there. Then delete it.
See it's simple good old fashioned computer detection work, so all you Computer Geeks stop rattling on about JAVA updates, internet options and other bollocks that doesn't work but just sound complex and posh.
You can do this in safe mode if you desire but I didn't and it was ok and now problem free.
