After I installed Antivirus, Norton detected a potential risk and advice me to fix it by itself. After I allow it to fix, it asked me to restart the machine. After I click to restart the machine, I notice an error message
" ipconfig.exe-Application Error The application failed to initialize properly (0xc0000005). Click on OK to terminate the application"
After windows xp reboot, the wireless connection doesn't work, though wireless connection works fine with my other computers. I noticed a thread "
Please help!! Norton screwed up my Internet and even after uninstall, still can't load a page!" I tried the flushdns. It still doesn't work. I removed the Notorn as suggested by customer representative. It still doesn't work. I don't understand what Norton had done on my machine.
