What is the most prevalent way that spyware makes it on to your PC? The reason I ask is that I am considering using SanboxIE. But it is not convenient to run my mail client in the sandbox as I frequently send and receive email and attachments that I must save. So I was wondering what the most popular means of infection are. EDIT: MODEARTORS PLEASE CLOSE OR DELETE. THERE IS A BETTER FORUM FOR THIS THREAD.
