Hello,
I have a Windows Home Server that seems to have been infected with something that is causing constant internet traffic from this computer. I've noticed occasional error "beeps" from the PC, and looking at the internet logs from my router, it appears to have a lot of "unsolicited" web traffic, which appears to have begun on Thursday. If I log in to the server and try to browse the web from it, I get occasional re-directs to sites like newsdaily7.com, onlinequickquiz.com, etc. I've run "Housecall" from TrendMicro, it found a couple of trojans, which it cleaned up, but the behavior continues. I installed Ad-Aware Free, it also found some issues, which it said it also cleaned up. But the behavior continues. I've had WHSClamAV installed for some time, but it doesn't detect anything. I've noticed ping.exe in my running processes with occasional CPU load. Unfortunately, DDS says it's not compatible with my OS, so I can't post a log from it. But GMER does run, so I'm attaching it's log, as well as a screen-cap of my router log for that machine showing internet traffic that I am not instigating. Are these of any use to give a clue as to what it might be? Any other tools I can use to get a decent log?

Thanks!

Just to update, TDSKILLER seems to have cleaned it. It found and removed a rootkit. Yesterday I blocked internet traffic to this machine from my router, but I could still see where it was trying to connect. Since running TDSKILLER, this has calmed down, and ping.exe is no longer running. Checking my event log I found some failed scheduled tasks due to the file not being there... checking the scheduled task manager showed a bunch of scheduled tasks (that I didn't create) pointing to a random file name in system32 that was presumably deleted by TDSKILLER. I've run an ad-aware scan, which found and removed a trojan. I will later re-enable internet access to this machine, and update if anything suspicious happens.

Another update: still no sign of ping.exe running unexpectedly, but I do still see some internet connection attempts. I know at least some of it will be legitimate: for example, WHS always tries to register with MS so remote access via homeserver.com is possible. Though I don't know how much, if any of the current attempts, are "suspicious".

We apologize for the delay in responding to your request for help. Here at Bleeping Computer we get overwhelmed at times, and we are trying our best to keep up.

  • If you have not done so already, include a clear description of the problems you're having, along with any steps you may have performed so far.
  • A new DDS and GMER log. For your convenience, you will find the instructions for generating these logs repeated at the bottom of this post.
    • Please do this even if you have previously posted logs for us.
    • If you were unable to produce the logs originally please try once more.
    • If you are unable to create a log please provide detailed information about your installed Windows Operating System including the Version, Edition and if it is a 32bit or a 64bit system.
    • If you are unsure about any of these characteristics just post what you can and we will guide you.

  • Upon completing the above steps and posting a reply, another staff member will review your topic and do their best to resolve your issues.

Thank you for your patience, and again sorry for the delay.

***************************************************

We need to see some information about what is happening in your machine. Please perform the following scan again:

  • Download DDS by sUBs from one of the following links if you no longer have it available. Save it to your desktop.
  • Double click on the DDS icon, allow it to run.
  • A small box will open, with an explanation about the tool. No input is needed, the scan is running.
  • Notepad will open with the results.
  • Follow the instructions that pop up for posting the results.
  • Close the program window, and delete the program from your desktop.
Please note: You may have to disable any script protection running if the scan fails to run. After downloading the tool, disconnect from the internet and disable all antivirus protection. Run the scan, enable your A/V and reconnect to the internet.

Information on A/V control HERE


We also need a new log from the GMER anti-rootkit Scanner.

Please note that if you are running a 64-bit version of Windows you will not be able to run GMER and you may skip this step.

Please first disable any CD emulation programs using the steps found in this topic:

Why we request you disable CD Emulation when receiving Malware Removal Advice


Then create another GMER log and post it as an attachment to the reply where you post your new DDS log. Instructions on how to properly create a GMER log can be found here:

How to create a GMER log


As I am just a silly little program running on the BleepingComputer.com servers, please do not send me private messages as I do not know how to read and reply to them! Thanks!
