Whenever I run CCleaner registry check, it shows a unique DLL, never the same between boot cycles, and the actual DLL file does not exist my drive. 

 

Here is a random example:

ActiveX/COM Issue InProcServer32\%SystemRoot%\system32\puwnnn.dll HKCR\CLSID\{E5B07C67-ABC0-A23C-677B-538540C9B336}

 

But there is no file puwnn.dll on my computer.

 

Other than some  extra COM SURROGATE processes, all other scans show nothing, I have Norton active and Malware Bytes active.

 

I can delete this registry entry, only for another one to show up next boot cycle.  Is there a risk?  How to tell?

 

Thanks.

Very weird, there might be a malware that is constantly dynamic and embeds itself as a registry. Have you tried going into Windows "Safe Mode with networking" and doing a scan there? Additionally, I recommend scanning with Malwarebytes, AdwCleaner, and Hittman Pro for more thorough malware check.

I do full scans using Norton and Malwarebytes, nothing unusual, Norton finds tracking cookies.  I also use the latest AdwCleaner, and it also does not catch anything that affects this symptom.  I can try Hittman Pro next, and also scans while in Safe Mode with Networking.  Thanks.

Cheers. Have you had any luck sorting out the issue? It is always good to write if a solution has worked. If someone has a similar problem in the future, they will know that it can be solved. If it doesn't work, it might be that CCleaner itself is detecting a false positive. Could also be cracked/other means obtained software that causes the panic. Considering that not a single anti-malware provider detected it as a problem.
