I would appreciate any help on this due to my lack of computer knowledge.

I have had Spybot S&D 2 for a few months now and today my scan decided not to open. This apparently only started after my sister told me that while she was on my laptop it suddenly stopped her music and played the same beat repeatedly. I have no idea what she may have done to it (if anything) because she is the computer smart child. I wanted to run a system scan but it will not open. I click the button and the icon flashes but it does not open or begin scanning. Nothing happens.

I have an HP laptop and Windows 7. If you need any other information please ask although you may have to explain what you're asking for.

Thank you to anyone with more knowledge than me!
