Dear BleepingComputer team

Would you please advice either I have problem or not and any solution

My Malwarebytes Anti-Malware IP guard alert infection IP 115.100.250.72 and 91.213.174.9 and block them although all my browsers are off
As I monitor the ports it says process svchost.exe912 is trying to connect to these remote address

I also found my IE and FF no more able to connect to drweb.com and malwarebytes.org although I still able to receive updates and uploads for these software.

Run-regedit is not blocked

Yesterday Anti-Malware removed following keys
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\option_1 (Rootkit.Agent) -> Quarantined and deleted successfully.
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\option_2 (Rootkit.Agent) -> Quarantined and deleted successfully.
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\option_3 (Rootkit.Agent) -> Quarantined and deleted successfully.

Now both Anti-Malware and DrWeb report the system is clear.

Thanks
Sergei

Looks like a buried Rootkit that is active.

About what we have found...
One or more of the identified infections is a backdoor trojan.

This allows hackers to remotely control your computer, steal critical system information and download and execute files.

I would counsel you to disconnect this PC from the Internet immediately. If you do any banking or other financial transactions on the PC or if it should contain any other sensitive information, please get to a known clean computer and change all passwords where applicable, and it would be wise to contact those same financial institutions to apprise them of your situation.

Though the trojan has been identified and can be killed, because of it's backdoor functionality, your PC is very likely compromised and there is no way to be sure your computer can ever again be trusted. Many experts in the security community believe that once infected with this type of trojan, the best course of action would be a reformat and reinstall of the OS. Please read these for more information:

How Do I Handle Possible Identify Theft, Internet Fraud and CC Fraud?
When Should I Format, How Should I Reinstall

We can still clean this machine but I can't guarantee that it will be 100% secure afterwards. Let me know what you decide to do.


To clean this we need a deeper look and a rootkit scan.,please go here....
Preparation Guide ,do steps 6 - 9.

Create a DDS log and post it in the new topic from step 9.
If Gmer crashes,skip it and move on.
Let me know if that went well.

Hello,

Now that you have posted a log here: http://www.bleepingcomputer.com/forums/t/302690/suspected-rootkit-infection/ you should NOT make further changes to your computer (install/uninstall programs, use special fix tools, delete files, edit the registry, etc) unless advised by a MRT Team member, nor should you ask for help elsewhere. Doing so can result in system changes which may not show in the log you already posted. Further, any modifications you make on your own may cause confusion for the helper assisting you and could complicate the malware removal process which would extend the time it takes to clean your computer.

From this point on the MRT Team should be the only members that you take advice from, until they have verified your log as clean.

Please be patient. It may take a while to get a response because the MRT Team members are EXTREMELY busy working logs posted before yours. They are volunteers who will help you out as soon as possible. Once you have made your post and are waiting, please DO NOT make another reply until it has been responded to by a member of the MRT Team. Generally the staff checks the forum for postings that have 0 replies as this makes it easier for them to identify those who have not been helped. If you post another response there will be 1 reply. A team member, looking for a new log to work may assume another MRT Team member is already assisting you and not open the thread to respond.

Please be patient. It may take several days to get a response but your log will be reviewed and answered as soon as possible. I advise checking your topic once a day for responses as the e-mail notification system is unreliable.

To avoid confusion, I am closing this topic. Good luck with your log.

Orange Blossom :thumbsup:
