Internet broken forced to use a proxy

I_M_Weasel · 14 Dec 2009 at 13:01

My PC cant connect to the internet anymore, when I look in internet options the lan menu is set to use a proxy server IP points to 127.0.0.1.
I can deselect the proxy setting and my connection works again but each time the pc starts this proxy is reselected and i have to disable it again.

I've scanned for virus/malware and nothings come up, any ideas on a perminant fix?

What port is the proxy using?

What happens if you open up a command prompt and type:
telnet 127.0.0.1 5555

if you don't have telnet installed, and are on vista/windows 7 try following this.

It says it cant connect to the host at 127.0.0.1 5555

Tried a different browser? It's not a fix, but the first thing I'd try.

I've tried IE8, Firefox and opera, non of them connect (they all do after I disable the proxy). I just can't get rid of the proxy setting perminantly, its back after each restart.

Then I'd be checking for malware.

No malware or virus showing, odd attack in that it breaks my connection to the outside world, you'd think a virus would want a way to report back.

Has Norton been anywhere near the system?

Dano · 14 Dec 2009 at 18:16

And what have you used to scan for malware?

I_M_Weasel · 14 Dec 2009 at 18:16

No its not got norton its got AVG on it and Ad-Aware Free edition.

Run Malware Bytes + MS Security Essentials. My two favourites. This happened to my Dad's lappy, some virus/malware changes his proxy settings and he couldn't connect to tinter.

Whats the OS?

Go in and check the local security policy.

Proxy setting should be in there

gpedit.msc

User config - windows settings - internet explorer - proxy

Is it in there?

I_M_Weasel · 14 Dec 2009 at 18:27

OS is vista32, pc's in work I'll have a look at the security policy in the morning.

teaboy5 · 14 Dec 2009 at 18:43

You sure work hasn't put this on to stop you accessing the web?

I_M_Weasel · 14 Dec 2009 at 21:23

No we don't have an IT dept and this pc is for web use. I think one of my co-workers was attempting to download video's from where he shouldn't and down loaded something worse, he wont admit it. Would make things easier if he'd just tell me where he'd been. (he wouldn't be in trouble with work)

This would only affect IE, but worth a check nontheless.

My malware alarms would be ringing a little at this point. If it's a managed laptop just hand it to your IT department.

Didn't notice he said he checked firefox etc

There's nothing important on this PC so a reinstall is not a problem, probably quicker to start over.
