Somehow picked up what I believe to be a nasty malware issue. I cannot launch Spybot or any security software. I also cannot enter safe mode during startup. I see the screen for safe mode, but cannot arrow up to select safe mode. I am at a total loss as to what to do now. Any help would be greatly appreciated. I am tired of all these so called security breaches windows popping up as well as it this bug launching my browser and going to some porn site.
