Hi, my name is Roger Karlsson. I've been running this website since 2006. I want to let you know about the FreeFixer program. FreeFixer is a freeware tool that analyzes your system and let you manually identify unwanted programs. Once you've identified some malware files, FreeFixer is pretty good at removing them. You can download FreeFixer here. It runs on Windows 2000/XP/2003/20008/Vista/7 RC1. (32-bit only).

If you have questions, feedback on FreeFixer or the freefixer.com website, need help analyzing FreeFixer's scan result or just want to say hello, please contact me. You can find my email address at the contact page.

Comments

Please share with the other users what you think about this file. What does this file do? Is it legitimate or something that your computer is better without? Do you know how it was installed on your system? Did you install it yourself or did it come bundled with some other software? Is it running smoothly or do you get some error message? Any information that will help to document this file is welcome. Thank you for your contributions.

I'm reading all new comments so don't hesitate to post a question about the file. If I don't have the answer perhaps another user can help you.

Seems like the malware authors have made a small naming update for their malware. sshnas21.dll was previously named sshnas.dll and often seen with files such as msa.exe, msb.exe, a.exe, b.exe and c.exe.

You can use FreeFixer to delete sshnas21.dll:

1. Download and install FreeFixer from http://www.freefixer.com/download.html

2. Launch FreeFixer and start a scan. It should be finished in about five minutes.

3. In the scan result, scroll down to "Registry startups". Locate the following item:

rundll32.exe C:\Windows\system32\sshnas21.dll,AllocConsoleA

and click its delete checkbox to the left. Don't check anything else for deletion, unless you are 100% positive it is malware.

4. Click Fix.

5. Restart your machine.

6. Start FreeFixer again and run a scan. Verify that sshas21.dll no longer appear anywhere in the scan result.

Did that remove sshas21.dll from your system?

Very annoying

@Dale: Try my removal instructions listed above:
http://www.freefixer.com/library/file/49296/#comment1942

That should also remove the error message that appears when rebooting your computer:

"RUNDLL
Error loading C:\Windows\system32\sshnas21.dll
The specified module could not be found."

Did that solve the problem?

Hello Roger,

I also had this malware on my computer and AVG removed it. I had the same error message as Dale, so I had FreeFixer to remove it did as you suggested in a previous post.
AVG popped up, telling me it deleted the malware and my laptop freezed out. A couple of minutes later I got a blue screen and a reboot. Since then, I have 6 little desktops on my computer (starting from rebooting).. I had a BIOS reset to default which cured it once but after another reboot the 6 little screens are back and I can't do nothing about it...

Do you have any suggestion?

Thanks,
Adrienn

It worked great for me thanks Roger. No more problems since then though I had to run both AVG and Superantispyware in safe mode to get rid of all the file infections...... all because I wanted to watch a video in firefox and thought I was getting an add on to allow me to do so.....

thanks again

Dale

I had a the same problem and AVG seems solves its, but at 5 minute interval announced me that I have this malware. I used FreeFixer and now all it's all right. Thank you very much.

Hi, I have this sshnas21.dll on my computer. The antivir guard gives me a warning but doesn't fix the problem. I've tried to follow the instructions and installed freefixer, but it doesn't identify the file (which is strange because i can browse to the path C:/windows/system32/sshnas21.dll and see the file).

Any idea? Whenever I do an action with a browser I get the message from Avira that this file tries to access the system!

I've got the "RUNDLL

@Alain: I think you can remove the sshnas21 error message with msconfig:

1. Click Start -> Run. Type in msconfig.exe and press OK.
2. Select the Startup tab.
3. Untick the sshnas21.dll entry.
4. Press Ok.
5. Restart your machine.

Did that remove the error message?

Thanks! The startup error does not show any longer, but now it seems that the rest of the Trojan virus is still working! NOD32 does not seem to find it, it's quite anoying.

Thanks again anyway Roger! (btw I'm eager to try the upcoming 64bit freefixer version soon ;)!)

Same problem as Alain! I work with x64 windows, removed sshnas21.dll with AVG, but still have an error message at start up. I tried to untick it in msconfig.exe -> Startup tab but didn't find the sshnas21.dll entry in the list...

Thank you for your time!
