I have a pc which came with Norton AV but I was given a corporate version from my company. I removed the old version and started to install the corporate version , 18.104.22.1685, only to find out that it was not compatible with XP. So I used the restore feature in XP and rolled it back. I am now in a twilight world between the two and I can't remove or install either of them, over the weekend things seem to have changed! I don't know if I have been hacked but my Norton firewall is displaying similar syptoms where it was fine before. I can only shut the pc down by holding the on button. I have scanned using AVG but nothing was found, also I am having to use my old pc as I can not get out on to the internet with my main pc. I assume that I need to edit the registry to climb out of the hole that I have dug but I am not that familiar with this. Any ideas for what I should try?
Thanks, in anticipation.
