Appears to be created courtesy of Adobe, to do with the Macromedia Shockwave 10 updater. Try killing the process using taskmanager, then locating it (should be in C
WINDOWS\system32\Macromed\Shock* wave 10\Postupdater.exe) and either renaming it, making it "read only", or deleting it completely.
Open Regedit, navigate to this key: O4 - HKCU\..\RunOnce: [SWHelper] "C
WINDOWS\system32\Macromed\Shockwave 10\PostUpdate.exe" 1014020 (if it is present.) It can probably be deleted, or you may want to try a restart, and see if it deletes itself.
Having done this, if it recreates itself, or if the file wasn't in the indicated place, that would be a bit sinister, but I think you should be good to go.
There are a lot of hits around the web for this one.
[edit, "wibble" should be read as "slash-colon".Or rather, colon slash.]
