A good tip if Sandboxie fails is to use a program called ESET internet security 6 (AKA NOD32) or higher, this is an all in one computer anti-virus anti-malware, anti-phishing, anti-theft program that i've been using since i've heard about it back when it was version 3 many moons ago, this thing literally stops anything dodgy you click on from downloading and has never once let me down even when i've purposely tried to download unknown viruses, it learns on the go and i highly reccomend it, Sandboxies will let you download the virus and run it but NOD32 will stop it before it ever reaches your hard drive. prevention is better than cure.
