Change from %SystemRoot% to %fystemRoot% Options

[spazntwitch]

Heads up! One of my client's computer had some major issues and I wanted to bring them to your attention. You may want to add the following registry changes to your MalwareBytes search engine:

HKLM\SYSTEM\ControlSet001\Services\BITS (Background Intelligent Transfer Services)
ImagePath changed to: %fystemRoot%\System32\svchost.exe -k netsvcs
Start changed to: 0x00000004 (4) -- disabled

HKLM\SYSTEM\ControlSet001\Services\wuauserv (Automatic Updates)
ImagePath changed to: %fystemRoot%\System32\svchost.exe -k netsvcs
Start changed to: 0x00000004 (4) -- disabled

HKLM\SYSTEM\ControlSet003\Services\BITS (Background Intelligent Transfer Services)
ImagePath changed to: %fystemRoot%\System32\svchost.exe -k netsvcs
Start changed to: 0x00000004 (4) -- disabled

HKLM\SYSTEM\ControlSet003\Services\wuauserv (Automatic Updates)
ImagePath changed to: %fystemRoot%\System32\svchost.exe -k netsvcs
Start changed to: 0x00000004 (4) -- disabled

Notice how it changed the 'S' in %SystemRoot% to an 'f' and disabled the services. It also made it so that no changes were saved using the Services.msc add-in by making those registry keys read only.

One of the first clues something was wrong was the fact that HijackThis listed BITS and Automatic Updates as an O23 Service but had the file path as only "C:\Windows".

Here's hoping you'll get the changes added. Just wanted to make your EXCELLENT product even better.

Thank you very much for taking the time out to report this.

Okay, so what if when you GO to these keys in Registry Editor and you try to fix this, an error dialog pops up:

Title: Error Editing Value
Text: (BIG RED X PICTURE) Cannot edit ImagePath: Error writing the value's new contents.

This problem became apparent when one of our users (at work) came to me and said they were getting pop ups. Well, we use Sophos Enterprise here and also MalwareBytes (great for those little things). Well, our AV policy is not very tight, it lets stuff run so we don't have 200 people a day asking us if they can run wuauclt.exe or not. I'm sure you can understand. But anyway... I found that this virus(es) messed with winsock, so I found a post somewhere else saying to use 'netsh winsock reset' and that worked so now I can actually GO to the website and download definitions.

Well, I want to get Automatic Updates working again mainly so he doesn't see a stupid bubble pop up every time he logs in. SOMETHING is keeping me from changing this registry value. What can it possibly be?

To modify those keys, you need to right-click them and choose Permissions. From there, add yourself with full control and then close the dialog box. You can now change the permissions.

[AdvancedSetup]

That may or may not work. It really depends on if there is Malware actively monitoring it and removing your permissions as soon as you change them.

True, I had already removed all of the malware prior to performing this action. Anyway, good luck in getting it to work!

[Aspirina]

Hello, I had the same problem and I solved it. It is a malware that installs itself in the folder %Systemroot%\system32\drivers and in this case the file was called 3d16ee25.sys. I don't know if it copies itself with the same name or uses a random one. The file registers itself as a system service in \HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services and it is really easy to find because if you step on its key you won't be able to read it. Anyway, you can restart your system in safe mode and easily remove the key. Be sure you don't have any other malware/downloader that can install it again but since I removed it i haven't had any other problem. If you don't disable this malware, it will keep on installing malware on your computer, so every time you perform a normal scan for virus you will find some.

Please let me know if this worked for you.

I kept the file of the malware so if some1 tells me where to upload it for analysis, I will appreciate.

[Aspirina]

Here is what you should do:

to check the name of the malware file (in case the malware uses a random name when installing) you should do this

- Go to Start -> Run and type REGEDIT.EXE
- Find this key HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services and walk over the keys you find here with the Down Arrow button of your keyboard. You will easily find it because you will get a popup from regedit telling you that the key can't be read. Write down the name of the key and then do the following (you can close regedit for now):

- Run Malwarebytes' Anti-Malware or some antimalware tool.
- Remove everything you find (if you have this malware, then you will find seneka and some other nasty stuff like crypts.dll).
- If it asks for restart to fix everything click on Yes.
- Restart your system in Safe Mode.
- Go to Start -> Run and type REGEDIT.EXE (again)
- Go to Edit -> Search and search for fystemroot in the registry (be sure to find EVERY match)
- In every key you find the value, you have to go to Edit -> Permissions and set permissions (total control) for you (administrator) then apply and double click on the key, replace %fystemroot% with %Systemroot% every time and then restart your computer normally.
- Just in case... run your antimalware program again, because the downloader can install it again after you removed the malware the first time, as it can download it and you won't notice (before starting in safe mode).

Well I wrote this because I couldn't find anything about before so I hope it works for you too. By the way.. malwarebytes anti-malware halts my system badly when performing a full scan in both drives (sometimes it finishes the full scan of the smaller partition completely but not always, so i think it may be the amount of files and the memory of my computer or something that can make the whole system freeze.) - Ah and I don't speak English very well so I hope you understand everything. I tried to do .. not my best but... I tried (?)

Aspirina - What was the point of finding the reg key that you can't see and writing down the name of it?

~B

That's the name of the file of the virus. Just take a note of the name of the key and then do a simple search with search of windows (you know how to do that) and then you can remove the file. Anyway you should first disable the virus from that key before deleting it. If you start Windows in Safe Mode you can access to that key and delete it because the malware won't load at start. And don't forget to set the keys you change to the normal permissions they have (that is total control for Administrators) with regedit.

[Aspirina]

Here I go again:

Here is what you should do:

to check the name of the malware file (in case the malware uses a random name when installing) you should do this

- If it asks for restart to fix everything click on Yes.
- Restart your system in Safe Mode.
- Go to Start -> Run and type REGEDIT.EXE (again)

HERE you should search in regedit for the key I told you to write down and delete it. Maybe you have to set total control permissions for this key but you can do it with regedit.

- Go to Edit -> Search and search for fystemroot in the registry (be sure to find EVERY match)
- In every key you find the value, you have to go to Edit -> Permissions and set permissions (total control) for you (administrator) then apply and double click on the key, replace %fystemroot% with %Systemroot% every time and then restart your computer normally.

I think this downloader has downloaded another downloader that is still active and I didn't find it yet (I just noticed it). Malwarebytes didn't detected it either. Somebody should let the downloader downloading to watch the other stuff it downloads to make the Anti-Malware detect them too. I will try to find it and upload it.

[crazyboy]

I had the same issue, been reading up on BITS and Auto update errors all night, this post definaly helped after i noticed the "S" in System was changed to an "F"..

Thx

[tintilla]

1) I have the same problem.
In my case the malware es called 4ebde4e8.sys.
The question is How Can I remove it.
Can MalwareBytes do that using the today new database version 1856?
or Do I need to follow the Aspirine solution?

2)Until now anybody, has tried using another antispyware - malware to solve this issue?

3) This infection slow my computer when I try to connect my computer to internet. Load a web page take a lot.
However, sometimes everything is with the normal speed.
It seems that the malware stops to slow my computer.....for a while

Best regards
HCOVA

This is a new malware so any antimalware program won't find it for a while. And you should get it out fast before it installs a new rootkit that I have, almost indetectable I can't find it I only know its possible names but I can't find a way to get a copy of it's contents because it changes its name a lot so I can't do anything.

[hcova]

Aspirina:
I tried to copy paste the malware you mention. This is located in C:\WINDOWS\System32\Drivers.....has you told us.
It can not be copied in the usual way.
The other characteristic is that it updates by itself in real time. I can see in windows explorer its "Date Modified" field. It has same creation date that the computer clock. !!!!! It is in a loop.
Question:
1) What can i do to avoid a spread of this malware in my computer. To avoid it installs a new rootkit.
2) Do you recommend me to keep the computer ON always? Avoid to shut down it.?

I am ver afraid of this issue, because I could loss my computer......i think

I am using NOD32 and PCtools Spyware Doctor.

Best regards
HCOVA

[Aspirina]

Are you trying to delete it when running Windows in safe mode? If you try to delete it running normal you won't be able to do it, if you have administrator privileges you should be able to delete it in safe mode or copy, and if you can't then try with some tool for file deleting, like the one included in malwarebytes antimalware or the secure shredder bundled with spybot s&d. But if you don't delete it in safe mode it will deploy again.
