can't connect to internet

[Dragon]

Here is what the comp is telling us:

Network Diagnostics for Windows XP


Windows cannot connect to the internet using HTTP, HTTPS, or FTP.  This is probably due to firewall settings on this computer.


Check firewall settings for HTTP port (80), HTTPS port (443), and FTP port (21).

 

I was working on this thing a bit yesterday and was having nothing but trouble with IE (pulling random pages, saying Google.com doesn't exist, etc)
She was running AVG Free but for some reason that has disappeared.  I installed Microsoft Malware and Security Essentials. 

The scans picked up and removed one bugger, sorry but I can't remember the name of it right now.  I went over the IE setting over the phone and all seems to be ok.  The strange part is that she can access e-mail, so I know it's not a complete DSL failure.  She called her ISP and of course they are blaming the newly installed programs.

I'm planning on looking at it again tonight, but I'm at a loss.  Any idea what I might be overlooking?  Other than the obvious get rid of IE and use Firefox. 

Thanks.

couple of things.

tools -> internet options -> connection tab click LAN make sure the proxy isn't checked.

double check this hosts file in windows/system32/drivers/etc

should only be 1 entry listed.

run malwarebytes, lots of nasty things can run redirectors

can you ping the router? the gateway? anything?

The web page redirection and AVG disappearing sounds like a trojan. There may be more malware than the one you found.

Proxy was checked, no address present, just port 80.  I had her change back to auto detect, no luck.

I'll run Malwarebytes when I get there.

I'm thinking your right.

I had to run out of there yesterday before the scans were done so I didn't get a chance to look any further.

well thats part of the problem fixed

Fixed the main problem.  Both the autodetect and the proxy were checked creating an issue.  MalwareBytes found 78 items.  All good now.
