server - Can not run php scripts anymore !

I had been running php script successfully for a year or so with WAMP but yesterday i noticed that scripts were not opening/running. When i go to http://localhost, the page just keeps on loading indefinitely. Of course, there is no errors in the scripts.

I tried:

• Re-starting All Services
• Re-installing WAMP
• Even tried easyphp (similar to wamp)
• uninstalled the suspicious softwares

When i tried "o localhost 80" command at telnet, it says "Connecting to localhost..." but it never connects.

Interesting:

Am able to run script inside PHP Designer (the editor for php) but not on browser using WAMP as said before.

OS: XP SP2 with Avira Antivirus

Any help will be highly appreciated as it is very important for me to be able to run php scripts on browser to finish some urgent tasks....

Update: Here is my apache log, i can't figure out what does it say:

Turn off anything running on port 80 ie Skype (you can run skype after wampserver starts but not before)

I have the same problem also happen to me in Internet explorer are you using that browser? If you are running certain addons in IE it will cause this issuse such as "AVG safe search" if i recall that was the one causing me problems... but you may want to disable add-ons and try that... try different browsers...

edit: one more thing: check out one of my tutorials on how to edit the host file you may try remove line 19 and save the file and then restart your server and try localhost again or your local ip 127.0.0.1
