this isn't the first time i've had to deal with something like this but this time around i'm unable to execute any applications on my pc. i tried rebooting in safe mode and then using sdfix but even that won't run. and because of this i'm unable to use anything like ccleaner, malwarebytes, or even make a hijackthis logfile.
any assistance would be greatly appreciated. i've already spent a few hours trying to tackle this myself but to no avail.
thanks to anyone who volunteers their time to help me out.
