I work in an IT shop and I agree that most folks are still cluelss about computers.  Knowing how to use software, send email, facebook or Google whatever doesn't make you computer savvy.  Though most think it does.  There is a whole other technical side which software over the years has incresingly masked to the end user.  I makes it easier for the ignorant to get themselves into trouble.

We lock down our environment hard to preven all this malware and junk.  We stay clean because we protect the users for themselves.  Most issues I see with malware are moslty related to browsing habits and the sites you visit.  I personally have friends and family that are repeat offenders for all this crap because they can't follow simple protocol when it comes to using the internet.
