Reoccuring Trojan.Agent.Generic

[illuminati999]

I reformatted my hard drive and just got everything installed fresh (nothing saved). For the past week it's ran with nothing detected until today. Several "Trojan.Agent.Generic" files and folders keep creating after they have been quarantined/deleted. I'm not sure what to do to get rid of it or if it's a false positive. Here is the info:

Hi illuminati999

My name is Aura and I'll be assisting you with your malware issue. Since we'll be working together, you can call me Aura or Yoan, which is my real name, it's up to you! Now that we've broke the ice, I'll just ask you a few things during the time we'll be working together to clean your system and get it back to an operational state.

• As you'll notice, the logs we are asking for here are quite lenghty, so it's normal for me to not reply exactly after you post them. This is because I need some time to analyse them and then act accordingly. However, I'll always reply within 24 hours, 48 hours at most if something unexpected happens
• As long as I'm assisting you on Malwarebytes Forums, in this thread, I'll ask you to not seek assistance anywhere else for any issue related to the system we are working on. If you have an issue, question, etc. about your computer, please ask it in this thread and I'll assist you
• The same principle applies to any modifications you make to your system, I would like you to ask me before you do any manipulations that aren't in the instructions I posted. This is to ensure that we are operating in sync and I know exactly what's happening on your system
• If you aren't sure about an instruction I'm giving you, ask me about it. This is to ensure that the clean-up process goes without any issue. I'll answer you and even give you more precise instructions/explanations if you need. There's no shame in asking questions here, better be safe than sorry!
• If you don't reply to your thread within 3 days, I'll bump this thread to let you know that I'm waiting for you. If you don't reply after 5 days, it'll be closed. If you return after that period, you can send me a PM to get it unlocked and we'll continue where we left off;
• Since malware can work quickly, we want to get rid of them as fast as we can, before they make unknown changes to the system. This being said, I would appreciate if you could reply to this thread within 24 hours of me posting. This way, we'll have a good clean-up rhythm and the chances of complications will be reduced
• I'm against any form of pirated, illegal and counterfeit software and material. So if you have any installed on your system, I'll ask you to uninstall them right now. You don't have to tell me if you indeed had some or not, I'll give you the benefit of the doubt. Plus, this would be against Malwarebytes Forums's rules
• In the end, you are the one asking for assistance here. So if you wish to go a different way during the clean-up, like format and reinstall Windows, you are free to do so. I would appreciate you to let me know about it first, and if you need, I can also assist you in the process
• I would appreciate if you were to stay with me until the end, which means, until I declare your system clean. Just because your system isn't behaving weirdly anymore, or is running better than before, it doesn't mean that the infection is completely gone
  This being said, I have a full time job so sometimes it'll take longer for me to reply to you. Don't worry, you'll be my first priority as soon as I get home and have time to look at your thread
  

This being said, it's time to clean-up some malware, so let's get started, shall we?

Is that the same computer you were seeking assistance with in this thread?

https://forums.malwarebytes.com/topic/231177-same-malware-keeps-coming-back

[illuminati999]

Yes. I wiped it clean and then installed Windows 7 65 bit (along with the software I use daily). I didn't get this until a program I was trying to install crashed/closed. It didn't finish installing. Being paranoid, I ran a malwarebytes test to see if maybe it was a contaminated file I tried installing. Sure enough, it detected this and nothing seems to stop it from creating again after I've quarantined/deleted it. Maybe it was coincidental, I don't know.

From where did you download and install your programs? Did you go online to download them, or did you have the installers saved somewhere else already (on a hard drive or else)?

[illuminati999]

I went online. I knew if I used anything from the infected hard drive, it could potentially be contaminate and make the long tedious process of reformatting done for nothing.

For the past week I've been doing about 10 scans a day on average and they always came back clean. It didn't do this until earlier today I had a failed install of a program (from online).

 

Also, when it quarantines the files and reboots, I'll do a scan right after and it comes back clean. But then I wait a few minutes later and then run malwarebytes again, only to not be clean and show you what is in the logs.

[Aura]

Can you PM me the link from which you downloaded that program?

Also, it seems that you are infected once more with a backdoor trojan. Sorry to tell you that, but it looks like you'll have to format and reinstall Windows again. Though there are files I would like to collect before you do, since I have another user with the same infection as you.

Thank you. Now can you .zip the C:\FRST\Quarantine folder, upload it to SendSpace.com and PM me the download link for it?

[illuminati999]

I pm'd you the link. I'm doing scans now and they keep coming out clean. Do you still advise me to reformat?

 

[Aura]

As with any infection of a backdoor trojan, my advice is always to reformat, yes. As soon as a system is compromised with a backdoor, the only remedy possible is a full format and reinstall of the OS.

[illuminati999]

I did another scan right before sending this message and it's still clean. Once I did a scan and realized it was infected, I would quarantine/reboot and within 5 to 10 minutes tops, a scan would show the Trojan.Agent.Generic in the results.

You're the expert and I trust your judgment over my own so I'll do whatever you recommend. I just noticed that in these "Trojan.Agent.Generic", they aren't listed as BackDoor like the one that I had in my first thread (where you advised me to reformat).

Malwarebytes Log.txtFRST.txtAddition.txt

[Aura]

I reviewed the logs in your previous thread, and you were infected with DarkComet, a popular RAT. Though it looks like it was a common stub.

https://www.infosecurity-magazine.com/news/autoit-makes-malware-outrageously-easy/

From the logs in this thread, I can see that you were infected with an AutoIT-based RAT, which I suspect is a modified version of DarkComet. All the samples you provided me, were forwarded to Malwarebytes' Research Team for further investigation and I'm also working on them on my side.

And I don't see traces of that infection anymore in your latest FRST logs, but like I said, I cannot say with 100% certainty that your system is clean.

[Aura]

Hi illuminati999,

Are you still with me?

[illuminati999]

Yes I am. Is there an update about the files I sent your way? A few days later and still my system is clean, no issues whatsoever.

 

[Aura]

They turned out to be part of another RAT, not DarkComet. But you were still infected with a backdoor trojan nonetheless.

[Aura]

Hi illuminati,

Are you still with me?
