Hi All,

 

I think I may be infected with something, possibly a botnet client.  Recently I've noticed steady stream of outbound traffic (aprox 300 - 500Kbps) originating from my PC.  Each time the destination IP is different and not one I recognise.

 

I consider myself an intermediate user.  I've scanned with AVG anti virus and nothing comes up.  Also scanned with Spybot S&D & Malwarebytes - again both clean.

 

The last "attack" was earlier today, and I ran these programs during the attack but it didn't find anything.  I've also got RUBotted from Trend installed but that failed to pick anything up.

 

The stream of outgoing traffic usually happens in the afternoon on a Monday or Friday (from what I've seen) which makes me think it's possibly a botnet client but so far, I can't find any trace of it!

 

Here is part of a Wireshark capture taken from today's attack - https://dl.dropbox.com/u/69515152/Capture.pcapng

 

In order to break the connection I either have to reboot the router or shut down the connection to my PC for several minutes.

 

OS is Windows 7 x64.

 

Please help - it's driving me insane not knowing what's causing it.

 

Thanks,

 

Stuart.

Ahh its a Google analytics infection and difficult it to remove on your own. Start a new topic about Google analytics infection,

 

 

Post a DDS log from this guide in that topic and we will get it out.

Please follow this Preparation Guide and post in a new topic.
Let me know if all went well.

How do I get help? Who is helping me?For the time will come when men will not put up with sound doctrine. Instead, to suit their own desires, they will gather around them a great number of teachers to say what their itching ears want to hear....Become a BleepingComputer fan: Facebook
