Hey just to be safe... You definitely want to be sure your dlls didn't get modified by some malware.
Mind sending the files that were getting truncated up to VirusTotal?  They should come back clean.
If not, then it's worth continued investigation.
 
We should post the checksums of the files.  I would use SHA1 rather than MD5 (the type of checksum hash used)
However, you can compute it and save off the results for later compare.  If we didn't change the file, then the checksum should be the same.

Keith, you guys should be following this issue, It does seem at this point it is McAffe 90% of the cases. 
 
It might be pertinent to make a statement to Sonar users if this can be verified officially. 
 
 

@ cactus music...amen brother.
lately, i've noticed mcaffe turning itself back on even after i disable it until i restart. 

Yeah, I started having this problem this weekend.  My system's nothing special...I'm on W10 1709.  I didn't have this problem before I was updated to 1709, (which was a couple weeks back).  In addition to DSDConvert.dll being affected, CWVideoEngine.dll was affected once as well.
 
An alternate method to recover would be to roll back a version, then update again.  This will help out folks who hadn't backed up the .dll(s) that got affected.  This recovery took me about 4 minutes to complete. 

Been using SONAR for 5 hours closed it down for lunch with no issues. Tried to start it again and immediately got C:\Program Files\Cakewalk\SONAR Platinum\CJLibrary.dll is either not designed to run on Windows or it contains an error? 

Merged with ongoing thread.

Will see tomorrow if the issue still occurs and if so will copy .dll file from back-up PC and see how far I get.

This happened to me this morning.  In Sonar - got out, went to get back in and got the CWVideoEngine.dll issue. Strange, since it was apparently modified while I was using Sonar! No other Sonar files were modified, last files modified on 10/25.
Yes, McAfee on board.

Just checked CJLibrary.dll it was updated yesterday when I tried to restart SONAR (When it failed) and is now showing 0KB in size
