[ubuntu] Error message when starting ubuntu 14.04

I have Ubuntu 14.04 on my laptop single real installation on Hdd (ok with dual boot). But only becourse my husband does not alow me to delete orginal. oh and there might be some older linux partitions on there but they may not have an boot enty anymore.

Every time when I start my PC just before Ubuntu destop apears I get the folowing Error message. "vbox client the virtual box is not ruing" I even deleted virtual box I think. But still getting this message. Since a few weeks even on an second linux computer a bit after instaling the ubuntu desktop.
Has anybuddy seen this and do I need to worry could it be that I'm . The Worry got bigger as it apeard on a second maschine becouse I think it apeart not the intance I installed the ubuntu desktop. Rater a few days or weeks after. Every thing I found online using the Duckduckgo search engine was just about a failig Virtual Box instalation nothing about having this message on a real single Hdd install.

Thanks alot for any answer
