I notice when I go view Task Manger to see what running I see a 2 background apps that say "COM Surrogate" and then it disappears. So I restarted the computer and it's there again and I right click right away to view it's properties. It is in C:\Windows\System32\dllhost.exe. Digital Signatures comes from Microsoft Windows. So people with Windows 10 can you view if you have the file in Task Manger. My computer is in ghost mode so nothing can be installed. Only time when it's not in ghost mode is to run updates. The only program that is install is products from Adobe and Keyscrambler from qfxsoftware.
The windows 10 came straight from microsoft website. According to search the web COM Surrogate is consider a spyware and in regedit the file is here AB8902B4-09CA-4bb6-B78D-A8F59079A8D5.
Please look into your regedit and let me know if you see AB8902B4-09CA-4bb6-B78D-A8F59079A8D5.
