I am running XP, AVG, Outpost Firewall Pro. I can access all sites except those for Spybot S&D - www.safer-networking.org & www.spybot.info - I get the response 'cannot find the server'. I have tried disabling the firewall and antivirus but it made no difference. It was suggested that I install IE7 which I have done but again no difference. Has anyone got any idea as to why I cannot access these 2 sites. As an aside on some sites I get [AD] instead of presumably a picture. Why? A new problem since installing iE7 is that when I access http://www.ordnancesurvey.co.uk/oswebsite/getamap/ and then access the map it should show the grid reference in the bottom left corner for where the cross-hairs of the mouse are. In IE6 it did so but in IE7 I just get 'done'. I have run AVG, Ad-Aware, Spybot & Windows Defender but there are no apparent problems.
