certmgr.dll
« on: March 21, 2008, 08:56:48 PM »
I have Pro version 4.7.1098 on a xp sp2 computer. When I run a scan it finds C:\WINDOWS\system32\certmgr.dll and says Unable to scan: The system cannot read from the specified device. I have had this happen for some time but did not think it was bad because it also show 0 infections for the scan, and because this does not show up if I do a boot scan. Can you tell me why this happens and if it is anything to worry about or is it just one of those things because of windows?

I would suggest you run and post a hijackthis log, because I found this

http://www.bleepingcomputer.com/startups/CertMgr.dll-20150.html

The hijackthis log would confirm an infection.

• Save HJTsetup.exe to your desktop.
• Doubleclick on the HJTsetup.exe icon on your desktop.
• By default it will install to C:\Program Files\Hijack This.
• Continue to click Next in the setup dialogue boxes until you get to the Select Addition Tasks dialogue.
• Put a check by Create a desktop icon then click Next again.
• Continue to follow the rest of the prompts from there.
• At the final dialogue box click Finish and it will launch Hijack This.
• Click on the Do a system scan and save a logfile button. It will scan and the log should open in notepad.
• Click on "Edit > Select All" then click on "Edit > Copy" to copy the entire contents of the log.
• DO NOT have Hijack This fix anything yet. Most of what it finds will be harmless or even required.

Hi slybo and oldman,

Consider the additional info on this dll, certmgr.dll, where you also mentioned this: http://www.bleepingcomputer.com/startups/CertMgr.dll-20150.html
and this info I also found:
http://www.castlecops.com/t204664-MD5_f95da7c5b3453ca4dff34e2c82ed5663_CertMgr_dll_New.html

The bleeping computer site shows it to be located in C:\WINDOWS\Media where mine is in system32. I also did a google search and find site that says it is a microsoft file. Do you still think I need to do hijack since I am having no problems?

No, you should be fine. Sorry about that. I did find it is a protected file, which is possibly why I can't be scanned. Though I haven't seen anyone else mention it.

Hi slybo,

You could fire this system32 file up to virustotal here: http://www.virustotal.com/
But I guess it is a legit system file, if you have this:
Certmgr.dll   5.1.2600.2914   457,216   23-May-2006   11:54   x86   SP2   SP2QFE

pol

PS It would not hurt you to attach a hjt log.txt file, because we would evaluate it for ye, even if that meant you could fix some empties you do not need any longer,

Forgot to ask if after you look at my hijackthis log do you think I still need to send the file to virustotal and if so give me a little information about what I will have to do as I have never done that. I had done a hijackthis log a few years back so that was easy. Thanks slybo

I looked at the virustotal.com and in the middle of the page where you upload a file it looks like all I have to do is browse to the file then upload, but does the upload remove the file from my computer? Do I need to make a copy of the file and send the copy? What do I do or after looking at the hijackthis do I need to forget about this? Thanks just wanted to post this in case you say to do this. slybo

Your log looks good. If you want to keep hijackthis you can. It won't do anything unless you run it. If you what to remove it, open hjt, click the misc tools button, slide the slider down, click uninstall. Go to the folder it was installed in and delete the folder. In your case, C:\Program Files\Trend Micro\HijackThis

If out of curiouity you want to submit the file to virustotal

www.virustotal.com

copy and paste the following into the upload a file box (one at a time if more than one file is listed)

C:\windows\system32\certmgr.dll

scroll down a bit and click "send file", wait for the results and post then in your next reply.

Just saw you post

No the file will not be removed from you computer. Yes that's how you submit a file or use what I posted.

I did the virustotal and from what I understand it looks good. In the result column for each company it had a dash - , I assume this means that nothing bad was found, is this correct. This is the first time I have used virustotal. Also at the top of the list it said Result 0/32(0%). So am I alright on this? Thanks for all your help. slybo
