    Just after loading a free trial for crisis 2 that came on a disc from a PC my Norton detected the ADH 2 Trojan. Do you think it came with the disc or came from the net?

    Is your Crisis installer legitimate? If you are using downloaded game, be sure to scan it first before installing.

    Just completed a virus scan from and this highlighted the following virus is showing up on my computer: “C:\tmp\MediaPlayerLite- is infected with Trojan.ADH.2”
    (NB: C:\tmp is where I download anything from the web before running it.)
    Should I be advising MediaPlayerLite about this too?!
    Not convinced that any removal plans tried so far are finding all the potential damage this trojan may have inflicted though.
