VirtualBox: Mom please stop getting spyware (Cheap VDI)

While I normally am able to avoid the desktop support role there is one person out there who guilts err.. convinces me to help her out. My mom. I'm not going to sit here and bash my moms computer skills, in all actuality she is pretty good with a computer. In the past she figured out how to add a printer and print something with Ubuntu by herself. The problem is my mom is a Windows user and she is the typical user who receives questionable emails and goes to certain sites that promise you win things but only infect your OS with spyware.
