My 'netstat' check is showing strange content

I posted this in the Network and Sharing section two days ago. Senior member 'Pauly' suggested that I post this here for further help. I am copying the contents of that thread below for your perusal and help. I disabled all the plugins and extensions in Firefox but cklads is still showing in the Command Window.

The website clkads.com started opening in my computer, a few months ago, when I clicked on a link in some other web page. It used to burst out in a new window and not as a pop up. I think I was being redirected. I blocked it using the local host 127.0.0.1, in the 'hosts' file. The blocking is completely successful. Whenever cklads tried to open, it opened as a blank window, with a message 'this web page cannot be found'. Now, even the blank page is not appearing. It seems to be perfect block.

Thank you.

My Question

My Operating system is Windows 7 Home Premium with Microsoft Security Essentials installed.

While connected to the internet I did a random 'netstat -f' check using the command window. Please see the attachment. What worries me is the foreign address, clkads.com, against the local address 127.0.0.1 As far as I remember, clkads is a web site that plant cookies, malware, redirect and collect information from the browser. Sometime ago I blocked this web site using 127.0.0.1 in the 'hosts'' file and the blocking has been fully effective since then.

What is the reason this is appearing against 127.0.0.1, in 'netstat' check? Please advice.

Answer 1 from Pauly

try netstat -ano this will give you internal & external ip +PID which you can cross reference to task manager to see the associated program, you may need to go to programs tab>view>select colomns>tick program id>ok

My response

I have done the check. Please see the attachment from Task Manager. The highlighted line is the one with 'cklads' PID from 'netstat -ano' check. This shows only when FireFox is open. 'Cklads' does not show in 'netstat' or Task manager, with IE or Chrome open.

The blocking has been fully successful for many months. In spite of that, this is happening.

Answer 2 from Pauly

Did a bit of research on your problem and it seems its quite commonly downloaded with codec packs and similar items but it seems its only a browser plugin add on have you tried disabling add ons/plugins on your browser. Also this seems to be browser specific, what browser do you use & have you tried other browsers ?

Did you happen to download a CODEC to watch a video?

No sir. I have never downloaded a CODEC.

Can I run AdwCleaner from a USB Drive instead of installing it in my computer? I have never run a programme like this before. Just a bit nervous about it! Specially an application that changes the registry entries.

Regards,

AdwCleaner is an executable file not an installation program . You may download it place it into a USB flash drive and run it from there.

When you click on the file to run, click the search button and post the results .... that way we can see what should be deleted.

Thank you for suggesting a computer scan. I did complete scans using Microsoft Security Essentials, Microsoft Malicious Software Removal Tool and Microsoft Fixit.WinSecurity. All these indicate my computer is clean.

Considering the results of the scans and other information I have received, it seems this problem has something to do with the 'hosts' file entries and is not a security issue.

Best regards,

Melita,

The Hosts file can get hijacked, and so can your DNS settings.

Here are two programs that may help you:

Repair Hosts File

Repair Winsock & DNS Cache


AdwCleaner is a very good and reputable program. The site from which this program is downloaded is knowledgeable and trustworthy.

We do not cater to trashy stuff. However, if you wish not to run this program, it is your decision.

Hello Cottonball,

Thank you for these links. I didn't believe that you would recommend any trashy programmes, as you mention in your post. All your help is very much appreciated. It is just that I don't want to run too many scans when it doesn't seem to be indicated at the moment. I will keep these options for any future necessity.

Kind regards,

Melita,

We understand your concern.

If you need assistance doing repairs manually, without downloading any programs, we will also be glad to assist you.

Otherwise, cheers!

Thank you for your kind offer. If and when the need arises, I shall certainly take you up on it. I have always had great help from your forum :).

It is just that I have this bee in my bonnet about running any programme in my computer. As far as possible I avoid doing it. If it is really necessary of course, I have no choice but to do it.

Best regards,
