Backdoor.Generic14.abvq Infection

Recommended Posts

Hi, my PC seems as though it has been infected by both the Win32/Katusha.A virus as well as the backdoor.generic14.avbq trojan horse. I have AVG 2011 paid edition as well as Malwarebytes installed in my PC and neither seem to be able to remove the infection. I also tried to online virus removal tool from ESET, which said it was successful, but it seems not so. The infections keep hindering my attempts to scan, download, or even load Malwarebytes; however, I was able to reboot the PC in Safe Mode with Networking. I had kept my Malwarebytes installation file installed on my PC, so I was able to reinstall it, update it and scan. It did find the infections and quarantined them. I tried deleting them, and was unsuccessful. I then restarted the PC in normal mode and repaired AVG and scanned again and the problems have continued. They seem to be associated with or activated with desktop.ini as well as Firefox. I don't know how much information I may be able to gather and post due to the resistance I keep experiencing on my PC (I'm posting here from another one) but any suggestions you have would be extremely appreciated.

============= FINISH: 23:47:14.92 ===============

The Malwarebytes' would not run or launch. I rebooted in Safe Mode with Networking and was able to reinstall and update the Anti-Malware program; however, when trying to launch it I encountered the same error. Again I rebooted in Safe Mode with Networking, reinstalled Malwarebytes and updated it. I then rebooted again in Safe Mode without Networking and was able to run the program. I just tried to grab the log and it won't open again. I will try again to reboot into safe mode and copy the log to post.

The GMER Rootkit Scanner also would not function. The scan would begin and the program would shut down within the first seconds of being ran. I also tried running that program in Safe Mode and Safe Mode with Networking; however, the option to Scan was removed from the application while the PC was loaded in those modes.

I also ran the TDSSKiller rootkit removal tool which also found two infections and indicated it has successfully "cured" the infection; however, the problems continued after reboot. Earlier today AVG identified a new infection which keeps recurring. The newest threat name is TR/Crypt.XPACK.Gen

At this point I'm wondering if the best bet would be to reinstall the operating system; however, I don't know what is infected that may transfer upon backup and be reinstalled in OS again.

Hi and welcome to Malwarebytes.

I'm afraid I have bad news.

Your logs reveal a backdoor trojan. A backdoor severely compromises system integrity.

A compromised system may allow illicit network connections, disabling of security software, modifying critical system files and collection and transmiission of personal identifiable information without your consent.

I recommend that you disconnect this PC from the Internet immediately, and only reconnect to download any tools that are required. If you do any banking or other financial transactions on the PC or it if it contains 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. If it were on my PC I would not hesitate for a moment to do so. 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

Should you decide not to follow that advice, we will of course do our best to clean the computer of any infections that we can see but, as I already stated, we can in no way guarantee it to be trustworthy.

Should you have any questions, please feel free to ask.

Let me know what you decide.

Hi Chris,

I actually did reinstall the OS last night. However, first I did sync my files with SugarSync's online backup storage. These were not application files, only data. I did also upload my Outlook and Quicken data files. I have since reloaded everything in my PC, including those files and everything is scanning and behaving well so far. Do you have any concerns or suggestions on that action which I should be aware of?

Additionally, other than waiting for something to popup again in the AV scanner, is there any way to determine from the logs where this infection may spread to or what types of files it compromises. Specifically, is there a pro-active way to check the other desktop which uses the same router, but is not connected via a home network, for an infection, other than waiting for it to reappear? I really don't want to have gone to all this work to have it begin spreading again. Also, could it compromise any type of hard drive receiving service from the router, such as my Windows phone or a Wii? Or a better question I guess, would be what is the likelihood of this happening?

Is there anyway to determine how I became infected in the first place? I have AVG Internet Security 2011 (paid edition). I was not happy to find the infections were able to get through. Any suggestion on ensuring this does not happen again?

Thanks a lot Chris for any info you can provide for me.

It's difficult to tell a lot of that at this point. I can tell you that it's incredibly unlikely to have spread through your router.

Backdoor trojans are not really the same as file infectors. Sometimes one includes the other but it's not mandatory. Backdoor trojans don't generally infect the actual files on their own; however, the network activity they can activate is what is problematic (I suggest reading about botnets if you get the chance). That's why I said in this case it would be safe to backup your photos, documents, etc., because they are very likely to be safe to backup.

I am of the opinion that security software with recurring billings to you are not necessary. I use Microsoft Security Essentials (free), and the PRO version of MBAM (one time purchase of $25 for lifetime protection), and I've never had an issue. With those, it's likely that this issue would have been prevented in the first place.

Here is my standard prevention speech:

Now that your computer seems to be in proper working order, please take the following steps to help prevent reinfection:

1) Download and install Javacool's SpywareBlaster, which will prevent malware from being installed on your computer. A tutorial on it can be found here.

2) Go to Windows Update frequently to get all of the latest updates (security or otherwise) for Windows.

3) Make sure your programs are up to date! Older versions may contain security risks. To find out what programs need to be updated, please run Secunia's Software Inspector.

4) WOT, Web of Trust, warns you about risky websites that try to scam visitors, deliver malware or send spam. Protect your computer against online threats by using WOT as your front-line layer of protection when browsing or searching in unfamiliar territory. WOT's color-coded icons show you ratings for 21 million websites, helping you avoid the dangerous sites:

  • Green to go
  • Yellow for caution
  • Red to stop

WOT has an addon available for both Firefox and IE.

5) Be sure to update your Antivirus and Antispyware programs often!

Finally, please also take the time to read Tony Klein's excellent article on: So How Did I Get Infected in the First Place?

Hope I answered your questions and do not hesitate to ask if you have any further questions.
