After downloading and installing Bullguard Internet Security V10 and running a virus scan (no virus or malware reported) carried out a restart as required and got a message "System Events Notification Service could not be accessed" Unable to start or restart any systems. Unable to edit or adjust any IP addresses or DCHP options. On checking found that there appeard to be a general failure and was unable to restart any essential services even after unenabling Bullguard Firewall and Anti-virus. Uninstalled Bullguard, but still received same message. The computer was unable to access internet aas it did not "see" the router however was able to access the internet via Explorer 8 by opening router IP and then selecting Google from favourites. was able to browse internet as normal Then tried a system restore, but the same problem persisted, so re-restored. Then tried run sfc_/scannow with Windows 7 disk in CD-ROM but no joy. Then tried a upgrade of Windows 7 over the existing Windows 7 to replace any corrupted or missing files, but no joy. as same message and conditions persisted. (In fact the new upgrade of Windows 7 was not successful) and returned the system to original configuration. Could see no option for "inplace upgrade" Am able to use programs but PC does not see Network Printer, or anything with an IP address. Please help - does this new a complete Clean install?

Since there seems to be a strong relationship to your current problems and the installation of Bullguard Internet Security, it would be eminently more logical to contact Bullguard Technical Support and/or go to the Bullguard forums @ http://www.bullguard.com/forum.aspx When there is a strong probability that some third party software has caused a problem in Windows, go to the publisher of the sofware and seek help. Don't expect Microsoft to know how to fix something broke by a third party piece of software!Please remember to click Mark as Answer on the post that helps you, and to click Unmark as Answer if a marked post does not actually answer your question.
