I had updated my virus scan with Norton Symantec (mistake) & it blocked nearly everything. Then a few weeks later, I was prompted to install Vista because I was missing .dlls. I did this, but was not able to license it due to the fact that again, Norton was blocking me from hitting the internet. After the 3 days to get it licensed was up, now I cant even log on to the pc and I get a message saying so. My machine did run windows xp. I have booted up in safe mode, but can not delete the anti virus software and can not find the new software that keeps me from logging on. HELP! I have no clue how to get this resolved. I know if I could log on to the pc I could delete this stuff, but right now I just need help.
