Yesterday at 16.40 I installed Internet Explorer 10 for Windows 7 for x64-based Systems. with an installation status of Successful. I also installed
Platform Update for Windows 7 x64-Edition (KB2670838) not sure what it is for!
I then re-started the PC and all appeared OK my usual Firefox browser was functioning as normal, and IE did appear to be ok, not that I use it much, just do not like it! I understand that it cannot be removed as some programmes need it.
I also run Safari which is started at Boot up.
This morning I was unable to access the net via any of these 3 browsers, from IE I got "Proxy Server is not responding", similar from Safari, and Firefox, but did get a message about the proxy server,from Firefox so had a look via Tools, Options, Advanced,Network, Connection - settings, "Use system proxy settings" was selected (is this usual?) and changed it to "Auto detect proxy settings for this Network".
I have never changed these setting before just gone along with the default as set when firefox is installed.
Firefox is now functioning correctly as far as I can tell, but not IE or Safari, I am unable to find a way to get them to work. Thunderbird did not appear to be affected by this problem.
So how do I over come the problems, and should I be worried that someone has entered my PC some how and changed the proxy for some reason.
My wife has a PC on the same LAN and is not experiencing the problems, She had NOT updated her machine as I did yesterday.
We are both running Windows 7 Home Premium. ZoneAlarm and Firewall on the Router the Wireless has the usual protection set on the router.
