Today experienced no access to any web-sites through wifi connection. Tried cable connection and no luck. Even when disabling the firewall, no luck.
Opened in safe mode with networking and seemed to get access to website using cable.
Restarted the machine again and again no luck. Ran a full scan with Norton as well as Malware Bytes which didn't find anything.
Had to uninstall Norton 360 which took a long while ( approx 16 minutes ).
Planning to re-install again over the weekend
