I've recently encountered a prob where my IE will not connect to my default start page (page notdisplayed etc) and a Microsoft message appears that the 'common client user session has encountered a prob ......etc'. After rebooting, I can't access the Internet - same message appears. The only way I can return to an active Internet activity on my PC is when I initiate a System Restore action. However, when I end my IE activities and 'switch off' or Hibernate, I encounter the same prob on return and so back to System Restore etc to get back to the IE. I've tried a full system scan & a winsoxfix action with no positive remedy. I've read some info that it can be relative to a Norton Security/Firewall fault or to other type security faults possibly caused by malware action. Has anyone experienced this type of failure and how did you resolve the issue? Any useful advice appreciated as this is really irritating.
