OMG!! I've got a insidious virus going on. My Dell Insperion, Vista OS, has been taken over by a bug that will let it boot to the desktop, but not allow any programs to run. Not only that, it won't allow me to scan before windows boots to find the problem. I'm running MSE, with Defender in the background. How can I scan for virus' before windows boots? I'm twistin' out!!
