Hi, Thanks for your reply. I have checked the TIF and it is in the correct place. I have however taken the extreme step of completely re-installing Vista as the machine was only taken out of the box today I have lost nothing(except if you count the hours I've wasted on it during today). Reinstalling Vista has solved the problem so far. I have been able to install Norton internet security and open IE without fault and the machine just "feels" better now.if you follow what i mean? When i first switched on the machine out of the box several errors occurred,can;t remember what they were now but I do wonder if they were the start of my previous problems.BUT as it stands right now I have not re-Activated Phishing filter nor have I re-installed any Windoze updates yet and feel a little aprehensive in doing so.
Maybe i should consider NOT installing the KB931768 patch. This is a very strange situation indeed as i have a Dell desktop PC running VistaHP which was purchased earlier this year and that has the KB931768 patch installed and runs absolutely fine.(fingers crossed). I also very surprised that MS have not yet issued a fix for this problem.
