I have some problem with bit defender 2012. After I installed the bit defender 2012, every time I open my pc, my wifi will auto disconnect or no internet connection. I have try uninstall the bit defender 2012, after that no disconnection happen. However when I reinstall back the Bit Defender 2012, the problem come back again. I had try setting the network adapter stealth mode off, generic yes, port scan off and also internet sharing mode on, but the problem still there. I get frustrated that every time I restart my pc the internet connection gone...
