there is a file in C:/Windows/system32 called aeagea.exe (is a hidden file) delete it!
while your at it, delete AEAGEA.EXE-1B528188.pf in C:/Windows/Prefetch
And i think you might have gotten this from divX (don't hold me accountable for telling you that, its just a hunch)
some other programs that it *might* be:
maya
SuperDVD Recorder
other DVD ripping programs
