Facebook won't load

Using Firefox on pc with XP, other pc's in the house are fine. Getting this message,
Proxy Error

The proxy server received an invalid response from an upstream server.
The proxy server could not handle the request GET http://www.facebook.com/home.php?.
Reason: Error reading from remote server
Apache Server at www.facebook.com Port 3128

I disabled the firewall and did a system restore

Why are you using a Proxy? In the settings for the network card, find the TCP settings and remove all Proxy info

I disabled the proxy on Firefox but I still get the same error. This is acting like some kind of virus

If jobeards suggestion don't do it, you might go to Tools>Options>Advanced>Network Tab & under Connection, click settings , make sure NO Proxy is checked. HTH

I'm treating it as a virus.

Ok, I'm on W7 & if you have java turned off (disabled) in Google Chrome, I had to copy the URL & paste it in the java exceptions area to get into facebook.
I would suggest using Firefox simply because you don't have to do the java crap.

Run your scans then. I have no problen going into facebook using firefox , SeaMonkey or useless google chrome.

Code:

The proxy server could not handle the request [COLOR=#ff0000]GET http://www.facebook.com/home.php?[/COLOR].
Reason: Error reading from remote server
Apache Server at [COLOR=#ff0000]www.facebook.com Port 3128[/COLOR]

The GET request above (I hope) is not literal but an attempt to make it readable
The actual access to a web server is GET / HTTP/1.1 which worst case would be redirected to GET /home.php? HTTP/1.1
The www.facebook.com port 3128 is bogus; 99.9% of websites are on port 80 - - certainly FB is.
As a proxy is involved, the port 3128 COULD be the proxy input port which then accesses the true port 80.

good idea.
btw;get a command prompt and enter NSLOOKUP WWW.FACEBOOK.COM. (should return 31.13.70.23)
give this to your browser https://31.13.70.23/

Found this with Highjack this
R1-HKCU\Software\Microsoft\currentversion\internetsettings,Proxy override=*.local
says it is not needed nor is it present in default install, possibly causing changed search page start page or search assistant

Returned 31.13.77.39

Well I got rid of it with Combofix and tdsskiller and by eliminating the reg entry. It was strange in that it was a virus on Facebook and once I cleaned it up on one computer, the rest were good as well. Merry Christmas all.

May I ask what security programs you have installed? Just curious is all.

I run Avast

Perhaps you should install http://www.techspot.com/downloads/568-spywareblaster.html
On my W7, I have Avast, spywareblaster, SAS, & m-bam. Update & run them once a week.
