I already asked this on another forum and didn?`t recieve any help

It is a totally weird problem. Basically someone might have hacked me some time ago
and there`s still some part of the code left.

Whenever i open any internet browser my registry gets modified , and a line for a proxy,
listening on a local network address gets added.

So someone wants ( wanted ) to turn my pc into a bot or zombie pc thats for sure.
The proxy listens on port 137 and 138 using a 192.168 address

When i boot the pc this proxy will not autorun and it`s not present.
As i said the proxy appears whenever i open a browser window .

I did panda online and several other virus scans...computer reported as clean.
The pc behaves totally normal .No suspicous network traffic on netstat.

There are no suspicious programms in my registry s "run " section. In fact it`s empty

I use win98 , java ,active x ,and visual basic disabled.

As you can see in the Hijack this log, the first line, R1, is the one, that gets added
whenever i open a browser.
This line is not present in hijack this after a reboot. it gets added later on.

Here is my log

Hello AlexHarvey and welcome to the BC HiajckThis forum. I see no signs of viruses or malware in the log. It is clean.

Proxy information can come from many sources. If the computer is on a network then the network could be supplying it (or if it was once on a network then it could be left-over from those settings). The 192.168 settings would point to a local network such as a home or small business network. Since the settings only appear when a browser is open then that would be the place to start. I would check the Netscape browser since it stores it's information in a file and not the registry.

For help with checking the various settings I would suggest the Web Browsing forum here: http://www.bleepingcomputer.com/forums/f/14/web-browsingemail-and-other-internet-applications/ . The settings are stored in different locations for different versions of the browser and someone there should be able to pinpoint the location for whatever browser version you have.


I do not respond to PM's requesting help. That's what the forums are here for. Please use them so that others may benefit from your questions and the responses you receive.
