This is a better option than HMP. 40 different opinions, and the box pops up quickly. For those that didn't read the other thread: For Firefox users, get the add-on "Download Statusbar", and in the AV tab add the executable for VT Hash Check. If you're certain you already have a clean box, put your real-time AV away and enjoy a massive malware database with no footprint for any future incoming files. VT Uploader is a good option too, but Hash Check is about twice as fast.
