Thanks for your reply. I apologize for not posting in the proper forum. I was in a rush to resolve the matter quickly and posted hastily.
I would like to report that I have resolved the matter to my satisfaction. I found that the service rikvm_C6F09094.sys is spawned by Cyberlink's kmsvc.exe (PC1 News
) and is "legimate". There is some question as to the purity of Cyberlink's motive and intent (tom's hardware
). For the benefit of others who might interested, I would note that the name of the process can be of the form rikvm_xxxxxxxx.sys, where xxxxxxxx is one of several strings of eight hexadecimal digits. Also, two of my PC's (both by HP), the Cyberlink software was pre-installed and the "offending" executable (kmsvc.exe) was of a different size (different version?) and found in other locations (subfolders of HP and LG).
I now consider my issue closed.
