    Just picked up Trojan Downloader.Zlob on full scan with AVG free 8.0 It was automatically banished to the virus vault where I emptied it out. Now the AVG overview says there is no Zlob any more. Ran the scan again, no trojan ….so is it really gone? Can I trust that?
    If I presume correctly that it has been killed (?) Is there anything I need to do next? Should I change ALL passwords, etc?
