sshnas.dll is malware and was installed on my system after running a faked Flash Player upgrade.

sshnas.dll is started every time a user logs on to the infected system, by adding the following command:

"rundll32.exe C:\Windows\system32\sshnas.dll,DllWork"


"HKEY_CURRENT_USER\SOFTWARE\Microsoft\Windows\CurrentVersion\Run, SSHNAS"

in the Windows Registry.

During the infection of my system, the following error messages also appeared, related to sshnas.dll:

Error loading C:\WINDOWS\system32\sshnas.dll
Invalid access to memory location."

Error loading C:\DOCUME~1\roger\LOCALS~1\Temp\\sshnas.dll
The specified module could not be found."

If you got sshnas.dll on your system I recommend removing it as soon as possible. I deleted it with FreeFixer.

How to remove sshnas.dll with Freefixer:
1. Download and install FreeFixer: http://www.freefixer.com/download.html
2. Start FreeFixer and click "Scan".
3. In the Scan result, locate items which mention sshnas.dll, and check its "Delete" checkbox. sshnas.dll usually appears under "Registry startups" and/or "Recently created or modified files" in FreeFixer's scan result. DO NOT check anything else for removal, unless you are 100% sure it's malware.
4. Click "Fix".
5. Restart your machine.
6. Start FreeFixer scan your computer again.
7. Verify that sshnas.dll no longer appear anywhere in the scan result.

Did this solve your sshnas.dll malware problem?

Here's the scan result from virus total which shows that sshnas.dll is detected by some anti-virus programs:

sshnas.dll was installed on my vista desktop in the same way you describe.
I deleted the file. then I scanned the hdd with avg free 9.0 but it didn't find anything. I cleaned the registry with piriform ccleaner v2.25. I still get lots of pop-up screens by ms internet explorer. whatever it is, it's still there.

I removed the trojan by downloading malwarebytes' anti-malware (mbam-setup.exe) and by letting it scan and remove the infection.
(my anti-virusscanner avg free 9.0 was able to detect, but not to remove the infection).
succes !

I downloaded Malwarebytes anti-malware in safemode with networking and ran it. It removed the file but it keeps coming back every 10mins. I downloaded the freefixer mentioned above but its not valid for windows vista 64bit apparently. Please help!

sshnas.dll is pretty good at escaping detection. I've scanned a new variant of sshnas.dll and only 3 of the 41 anti-virus scanners detected it at the time of writing:

if you cant delete with anti-virus software, try to delete it manualy, then delete if from your recycle bin then do this...

go to "run" type in "regedit" (windows registry editor) and go to "HKEY_CURRENT_USER\SOFTWARE\Microsoft\Windows\CurrentVersion\Run. right click on "sshnas.exe" and delete. it worked for me and it stopped all pop-ups and such.. hope this helps..

I tried CCLEANER , a free program (it´s mandatory on my computers). Clicked on REGISTY, ANALYZE and START CLEANING. And: problem solved ! Think, it´s the simpliest way to get rid of the ssnhas.dll entry.

MATTHEOH Above is Correct, but there are TWO, not one occurances in your registery. Do as per below.

"go to "run" type in "regedit" (windows registry editor) and go to "HKEY_CURRENT_USER\SOFTWARE\Microsoft\Windows\CurrentVersion\Run. right click on "sshnas.exe" and delete. "

"go to "run" type in "regedit" (windows registry editor) and go to "HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Run. right click on "sshnas.exe" and delete. "

That should stop it from reproducing.

I followed these prompts:

"go to "run" type in "regedit" (windows registry editor) and go to "HKEY_CURRENT_USER\SOFTWARE\Microsoft\Windows\CurrentVersion\Run. right click on "sshnas.exe" and delete. "

However, there is no sshnas.exe in the list. But I am definitely getting the error box everytime I log on. Any other options I have?

Had the same problem. Managed to get rid of this trash in this way (I have Win7):
1. Go to "Start", then "Run" - type in "msconfig", click OK.
2. Once the System Configuration Window opens - go to submenu "startup" (in my particular case among other items listed there I saw one definitely very strange - called "Los Alamos", manufacturer details - unknown). Deselect/Remove the tick in front of this item and press ok.
3. Reboot the machine and start-up in Safe Mode with Networking.
4. Once Logged in (you must be under Admin Account or have administrative rights) - go to C/Windows/System32 - find "sshnas.dll" and delete it.
5.Finally, also go to "Run" type in "regedit" (windows registry editor) and go to "HKEY_CURRENT_USER\SOFTWARE\Microsoft\Windows\CurrentVersion\Run. If you see any lines with anything of the following mentioned: "Los Alamos", "jkk.exe", "jkl.exe" or "sshnas" - delete the lines and close the registry editor.

Hope this might help. Important - if you are not a skilled/advanced user it might be better to opt for "Free Fixer" mentioned above or a similar program.

P.S.: there's no ideal antivirus existing - Windows Defender kept popping up every 10 minutes with the threat detection message - however pressing the "clean system" button was of no use and resulting in another pop-up 10 minutes later. I also have KIS2010 (Kaspersky Internet Security) running on my PC with the latest definitions updates at the moment - it failed to detect the threat even during the full scan of the system. So had to google a bit and remove the threat manually))). (Having wasted a couple of hours though)

You call it : sshnas.dll, my pc names it:
Also, these files belong to this version:
Delete these files (not Rundll32.exe, you need to fix that...) and virus is gone!
Try contacting Microsoft for support on Rundll32.exe...
