Has anyone working with Macbook Pro noticed when watching something that a popup comes from Adobe flash player asking for permission to use some space for a file they want to download giving you an accept or denie and when you try to denie it will not accept and go away.
I did not think you could get a virus on a Mac Book Pro.
They can be passed from Windows user. They may not infect your machine, but anything is possible. Anytime something BAD happens it is usually because the computer owner did something foolish, downloaded something risky, or tried to use a "free" download of software that is not free.
