My system:
AMD xp2700@333FSB / 512 MB RAM
Windows XP Pro
Comcast Cable broadband
D-Link Wireless Router 2.4 GHz / D-Link Wireless nic card
Firewall: Zone Alarm free issue
Decided to try Avast free AV, I heard it was good. Soon as I installed it and it loaded for the 1st time I lost access to the internet: at first the Comcast icon in my system tray showed a red X indicating disabled, and about 45 seconds later the X disappeared and the normal, Enabled icon re-appeared. My wireless D-Link nic card is working - the green indicator lamps on the card are blinking green/normal, the system tray D-Link and Comcast icons shows receiving full signal from the router, the firewall is normal and giving me no messages, but Inernet Explorer and Outlook Express keeps telling me I am offline when I try to access the internet. All my other computers on my home network system are accessing the internet fine.
Before this I had Zone Alarm installed and my internet access was perfect for two days.
Any suggestions?
