Was surfing web & had a AVG warning come up for a bad site. Followed on-screen directions. Ran both AVG & Malwarebytes Anti-malware & cleaned up system. Since then when I try to use the Curse.com client or World of Warcraft, I get a message that the Firefox proxy isn't compatible with these programs. I did not set a proxy (that I know of) unless it was done during the AVG or Malwarebytes setup. I have rebooted, shut down & restarted router - no luck. If I configure FF to not use a proxy, I can surf, download apps & repair exe files but can't load them due to same error. If I set FF to automatically select proxy, I can't connect at all. I uninstalled both AVG & Malwarebytes & turned off XP firewall. Still no luck. Got the MS Fixit thing for proxies, can't run it due to same error. The Curse client was corrupt, removed & downloaded new can't run it due to same error & the WoW repair exe is the same way. XP firewall is back on.

You can find the connection settings in Tools > Options > Advanced : Network : Connection If you do not need to use a proxy to connect to internet then select No Proxy

See "Firefox connection settings" in Server Not Found - Troubleshoot connection problems

That's what I have set now and I still have the problem described above. FF runs fine, anything else that needs a net connection doesn't. Calling the Net service provider and seeing if they can find something.
