Right, a daughter has got this trojan (Joker - varient, as yet unknown), that apparently has stopped the Windows XP from loading properly and won't respond to F8 to get into safe mode! Does anyone have any ideas of how to get round this, so that it can actually be removed? I haven't yet seen the computer, so don't have many details. All I know is that it puts up a screen when the desktop loads, saying something like pay 'x'-amount to have it removed! Daftly, she only has the Admin account set up! As I get more details, I'll amend this post. As usual, any pointers in this grately received!!......except a fresh install!
