Hi, After fresh installing my PC, the only thing I did was adding Noscript, Adblock and Downloadhelper to Firefox. MB found Trojan.ZBot in Kaspersky's Sandbox Folder. Wasnt possible to attach the supposed file - .autoreg. Never had any Problems with MB and Kaspersky's Sandbox or AddOns. Is it a false positive? Thanks for your help!
