First make a 4shared account if you havent already. Under the name of the file you are downloading should be a rectangular download button, on mine its next to a share and add to my account button. Then after that you should see 2 download buttons. One says priority download with 0 seconds and a free download button with 20 seconds. Click the 20 second button and you should be good. I've never gotten a virus doing it this way.
