Yeah...the trojan I had was a weird one too. It took down the internet...(I dunno how to explain it, but basically wouldn't let me surf the net on the computer) It disabled System Restore, meaning I wasn't able to use it at all. For some bizarre reason it took over my wallpaper too. o_0 It changed it to some box saying that you should scan for any viruses and that the network or whatever has been disabled until the virus is removed. I guess I could say my dad (when he looked at it) called it a joke, it wouldn't even let me change my wallpaper back. (unless I went to the image itself, lol) All this and at some random point this system window pops up and reboots the computer in a few seconds.
No clue what the deal was, we tried everything...all was left to do was wipe my computer out...took forever, I missed my computer. But now its back. (in an upgraded everything too. xD)
