Repeated IP block to; 31.184.192;

Recommended Posts

Please please help: After my last MalwareBytes Premium update/install it seems I now keep getting repeated IP blocks popping up (outgoing IP blocked); the calls are mostly to; but also to 31.184.192;, and to some search site it seems. I found via Google in St. Petersburg (!).


So I read various threads here but don't see a consistent step-by-step what do about it. The scary parts: (1) I don't recall opening anything questionable, (2) it happens intermittently, say every few hours, but when it does the pop-ups keep popping up; (3) multiple instances of DLLHOST are running. I worry this is a backdoor somehow.


I am attaching here my FRST and other scans. Any help and advice is GREATLY APPRECIATED! What exactly are we looking for in FRST log?

They call me TwinHeadedEagle around here, and I'll be working with you.
Before we start please read and note the following:

  • Limit your internet access to posting here, some infections just wait to steal typed-in passwords.
  • Please be patient. I know it is frustrating when your PC isn't working properly, but malware removal takes time.
  • Don't run any scripts or tools on your own, unsupervised usage may cause more harm than good.
  • Do not paste the logs in your posts, attachments make my work easier. There is a More reply options button, that gives you Upload Files option below which you can use to attach your reports. Always attach reports from all tools.
  • Always execute my instructions in given order. If for some reason you cannot completely follow one instruction, inform me about that.
  • Stay with me to the end, the absence of symptoms doesn't mean that your machine is fully operational.
  • Note that we may live in totally different time zones, what may cause some delays between answers.
  • Do not ask for help for your business PC. Companies are making revenue via computers, so it is good thing to pay someone to repair it.
  • If I don't hear from you within 3 days from this initial or any subsequent post, then this thread will be closed.

:excl: I can't foresee everything, so if anything unexpected happens, please stop and inform me!
:excl: There are no silly questions. Never be afraid to ask if in doubt!

Dear Trusted Advisor: Thank you (!) for getting back with me; I studied your (and other's) responses on this forum to similar topics, and followed the step you described in that thread. Long story short, ComboFix detected this (from the log file):

CLSID={AB8902B4-09CA-4bb6-B78D-A8F59079A8D5} - infected with Poweliks and removed.
You should verify if current CLSID data is correct:
    (Default)    REG_SZ    Thumbnail Cache Class Factory for Out of Proc Server
    AppID    REG_SZ    {AB8902B4-09CA-4bb6-B78D-A8F59079A8D5}
    (Default)    REG_SZ    c:\windows\system32\thumbcache.dll
    ThreadingModel    REG_SZ    Apartment


(I verified that the other ID's math what I have on other clean computers)


Note that comprehensive scans with MWB or Microsoft Security Essentials revealed nothing; reading through the FRST logs I found some old references in the registry to FunMoods (adware, junk bars) which I removed.


After running Combofix, I have not had any problems for the last 24 hours on-line (before it would pop up every few hours at least).


Here are some questions I still have: How did I catch this? I cannot recall installing anything or opening anything questionable. I only installed the latest MWB, and after I did that for a short while the program would not allow me to turn on real-time protection. After a few hours I rebooted and it started working again.


How can I prevent this from happening? How did I catch this?


PS: I changed all my passwords from another computer.


Thanks for your help; I will for sure make a donation to you guys. This site saved me a LOT of hassles and time.

I don't know for sure, as I have spotted the main source of infection are torrent sites. But, this infection is common problem these days, 50% of cases I've been working on are infected with this malware. MalwareBytes Premium is a good way to stop this infection, but again, watch what are you doing on the internet.



 I would like to see ComboFix report please.

The Importance of Software Updating:


In order to stay protected it is very important that you regularly update all of your software. Cybercriminals depend on the apathy of users around software updates to keep their malicious endeavor running.
Operating systems, such as Windows, and applications, such as Adobe Reader or JAVA, are used by tens of millions of computers and devices around the world, making them a huge target for cybercriminals. Downloading updates and installing them can sometimes be tedious, but the advantages you get from the updates are certainly worth it.

Recommended additional software:

icon_arrow.gifTFC - to clean unneeded temporary files.
icon_arrow.gifMalwarebytes' Anti-Malware - to scan your system from time to time in search for malware.
icon_arrow.gifMalwarebytes' Anti-Exploit - to prevent plenty of mostly exploited vulnerabilities.
icon_arrow.gifMcShield - to prevent infections spread by removable media.
icon_arrow.gifUnchecky - to prevent from installing additional foistware, implemented in legitimate installations.
icon_arrow.gifFiheHippo.com Update Checker - to keep your programs up-to-date.
icon_arrow.gifAdblock - to surf the web without annoying ads! 

Post-cleanup procedures:


Download DelFix by Xplode and save it to your desktop.

  • Run the tool by right click on the 51a5ce45263de-delfix.png icon and Run as administrator option.
  • Make sure that these ones are checked:
    • Remove disinfection tools
    • Purge system restore
    • Reset system settings
  • Push Run.
  • The program will run for a few seconds and display a notepad report. You do not need to attach it.

The tool will also record healthy state of registry and make a backup using ERUNT program in %windir%\ERUNT\DelFix
Tool deletes old system restore points and create a fresh system restore point after cleaning. 

My help is free for everybody.
