iMac unable to connect to internet

Hi. I had this problem immediately after installing the latest update. I was happily browsing the web and then right after I installed the latest update, I couldn't connect to the internet! Neither Safari nor Firefox, not even Yahoo Messenger works. The WiFi network's working fine - I am able to connect to the internet with my other devices. I am even able to use the internet with the Windows part of my Bootcamped iMac. Nevertheless, I've unplugged the modem and router for more than a minute, I've rebooted, I've run the network diagnostic tool (which said I am connected to my WiFi network) - still couldn't connect to internet. Please help!

iMac (27-inch Mid 2011), Mac OS X (10.7.5)
