Just for reference, another problem exists after this erro message has been displayed. Everything I do after this without shutting down works very slow indeed. Before programmes open in a matter of seconds, so does my spyware and antivirus programmes to see if there is a problem. These take minutes to open and to run.
This problem only happens when I am on line clicking on links people have sent me to watch. Saved files normally run ok unless I have been on line.
Any help would be appreciated.
