Problem with a trojan

i’ve got a reall problem latelty with this TrojWare.Win32.Downloader.Agent.~AJK@1582157
i can’t get rid of it
i scaned it with comodo several times it always finds something but can’t permamenlty erase it

what should i do?

If you think its safe, add it “Ignore > Add to My Own Safe Files”.

Else, check with “”.

Alternately, submit the file to comodo for analysis.

umm i think i wrtited it wrong
i meant it deletes some files with this trojan but iit finds antoher one after like 30 mins and it can find like 20 files a day like this

i’m asking how to get rid of this bug becouse although i scan the system it stays somewhere

If you are the administrator and didn’t set this yourself, you should place a check against this item in HijackThis:
O7 - HKCU\Software\Microsoft\Windows\CurrentVersion\Policies\System, DisableRegedit=1

Then press ‘Fix Checked’.

Hopefully this is what is preventing the removal of the malware.

If you are not the administrator you should ask them first.

I tried to remove it with hijack but when i scan again it’s still there same witth mbam it finds the bad regiteries i try to remove them but after reboot it’s still doesn’t work.
And i have the administrator acount.

You could try this, but I have no personal experience of it so at your own risk:

I wonder if someone managed to fight off this intruder. Like with the thread opener Comodo reports this TrojWare.Win32.Downloader.Agent.~AJK[at]1582157 as being present. But thing is it reports the virus in some exe files in the Temp folder of my user which try to execute themselves into the memory BUT no all of them. So some of the exes do manage to load and with the Task Manager disabled I have to kill them either from command line (with /f option otherwise it’s locked!) or with third party software (like Process Explorer). Nevermind this exes though - they try to mine information but the real problem is that something downloads them as soon as I connect to the Internet and Comodo never identifies this activity (i.e. some process is trying to connect to some host and download stuff). I’ve scanned with Hijackthis but there are no suspicious files which are to run when the system start and also there are no suspicious processes running other than the aforementioned exe files which I kill and the fact that when I try to go into safe mode results in an error and an immediate restart leads me to believe that some system files might have been tampered with by this virus. I believe I got infected when a friend of mine put his usb flash drive into my computer…
PS: I’ve also tried Spybot S&D and Superantispyware and they too didn’t eliminate the culprit.

Please also try running Bitdefender. The tutorial has been updated to What to do if you’re infected - eXPerience Rev.3

It sounds like there may be some cloaking going on (rootkit). When scanning with Bitdefender did not work you can try the anti rootkit tool GMER . It is a bit of a Spartan tool.

Malwarebytes' Anti-Malware 1.37 and Database version: 2232
Malwarebytes is now at version 1.38 and database 2407

An alternative is to try Avria Free version, it has a 99% detection rating

also after updating the AV software, I would run it in windows “safe mode”
You can access safe mode by doing this (for most computers)
1)shut down computer
2)Power on compuer
3)The second you power up the computer, keep hitting the “F8” key until a new screen comes up
4)When new screen comes up, go to “Start in Safe Mode” (NO NETWORKING)
5)Run Malwarebytes 1.38 and remove infections
6)Then run avira and clean what it finds
7)Repeat step 5 and 6 again to make sure none of it comes back
8)Log off the computer and restart in normal mode
9)If everything is fine, delete all the “system restore backups” and create a new one

Hope this helps :-TU

Well I was about to write some stuff about how undetectable this thing is but since Comodo regularly detects mipmkn.sys as an uknown malware and I delete it and then it is there again upon restart I’ve checked the DDS log and noticed a service name dabp470n5 which is apparently a part of a virus It worries me that it could probably be some newer modification than the one I’ve linked but still I will try to clean it. But with so many deleted registry key it won’t be easy even if it is the correct virus :frowning:

Try searching the registry for mipmkn.sys and dabp470n5 and see if you find references to other file(s) they may be protector files.

When you can find processes with Process Explorer you can suspend them. That will allow you to erase them on disk and to erase the registry keys.

When that doesn’t help try the mentioned rootkit scanner gmer.

Well it seems as if it really is that virus but I still can’t clean it. I can’t search through the registry because it’s disabled along with task manager and the virus is persistent so when I change something of it’s settings it changes it back in a matter of seconds. With gmer I can browse through some part of the registry but it’s very limited. I scanned online with bitdefender and it cleaned off a lot of files (about 600) infected with this Win32.Sality.OG but as the infection is apparently active in the system this isn’t a lot of good. The virus also deletes the [BootSafe] registry keys so when I try to go safe mode it BSoDs. This is getting pretty irritating >:(
PS: there is even a thread about this virus in this very subforum but I believe Comodo still has problems detecting it as the thread is from 14 jun and I’ve come to the conclusion that the infection occurred 15 jun 10:20 PM (although to be honest it’s not me who is maintaining this computer so the anti-virus definitions may not have been updated)

I took a look at the information by ThreatExpert. It is picked up by Ikarus (which is now part of A Squared anti malware scanner). You can try to scan with A Squared and see if that can handle it. Or try the trial version of Kaspersky. Also try the scanners mentioned in What to do if you’re infected - eXPerience Rev.3 and make the described Hijack This log.

I also found a removal tool by AVG: Free Virus Scan & Cleaner | Free Malware Removal Tools | AVG .

I cannot guarantee these tips will work as malware evolves. When the scanning does not work I will give you a couple of url’s for boards specialised in removing malware using a Hijack This log.

Thanks for the assist. I’ve tried the a^2 software but in a rather strange manner the computer restarted so a conflict with Comodo may have occurred. Also this AV don’t offer disinfection but only deletion. So I’ve run a second bitdefender on-line check and clean sweep and it seems that after it cleaned at least MOST of the files (well at the very least those which are in the autorun) the virus seems to not be reemerging after a restart. So now I will reinstall Comodo (in case it has been compromised) and try to seek out and restore all of the damages this virus did. I’ve added a SafeBoot key to the registry (not empty of course :D) and will see if it manages to boot in Safe Mode now. I will also set in gpedit.msc (Group Policy) autorun to off on all devices as to hopefully evade such infections in the future (coming from the usb drive).

Good luck and keep us posted.

With malware infection it never hurts to try multiple scanners. Using a trial version of paid programs may help. A2 and CIS live together happily here; I have A2 on demand only.
