Apache server not serving pages

[vinay tyagi <vinayex2@xxxxxxxxx>]

Hello,

I am using wamp stack on windows xp.

Lately I installed norton 2012 trial antivirus but uninstalled it and

moved back to my free avast antivirus.

Now my wamp is not serving pages.

Everything is working fine

I have checked with netstat that the address/port (0.0.0.0:80) is used by httpd.exe

Apache error log is

resuming normal operations

[Fri Jul 15 22:35:07 2011] [notice] Child 3736: Starting thread to listen on port 80.

which seems fine to me.

I ve tried disabling my firewall and turning off my antivirus

I've changed my port number to 8080. 

It seems something is refusing access to apache as it is running fine.

One more thing I could not disable my firewall from the GUI. i had to use  cmd services.msc.

Please Help..
