Everytime I get knowledge of such an article I wonder how difficult it is to only use secure websites for downloads. If I want to get piece of microsoft software (okay, bad example, I do NOT want to get any microsoft software) I won't go to zdnet. If I want to get a firefox I won't go to freesoftware-downloads-after-registering-and-then-have-to-pay-for. From my point of view it needs neither a high school grade nor black magic to find the secure distributor of a piece of software by just making logical thoughts before using the left mouse button.
