Hi : ) !!! - OS X 10.10 affected Virtual Box, any suggestions?

Hi,

Since the time I had an ibook G4 and now a 13" MBP,
I needed to have a Virtual PC. After the ibook G4, I
used Virtual Box from Oracle, instead of the Virtual
PC. Yesterday, I updated from OS X 10.6.8 to 10.10
and the Virtual Box is 'gone'. The icon still appears,
but it doesn't work. Any ideas of what I could do?

Thank you, kind regards,
