DONT DO IT. If anyone sends you a zip file don't download it. And DO NOT OPEN it. YOu might not notice anything might be fine for a couple months a year whatever. And then someone is going to activate the virus or worm. Then all of a sudden everything on your server is encrypted and you have no info what so ever. Not just your computer but your sever. Then you either pay to have it professionally cleaned out and find the good files that have been renamed. Or you pay the people who gave you the virus and they give you back all your stuff.
