If you want to not see the abrt generated alerts on the desktop you
could try removing the abrt-addon-kerneloops package (I have not tried).
The BUGs will still be there but abrt will(should?) not report them. 

If you want to actually _fix_ the underlying problem, well, that is the
job for a kernel guru. I don't know which version of vbox you are
running, if the kernel module is open source (I don't remember) then
there would be hope, if there are closed components then there is no
hope unless the vbox developers themselves fix the problem.
