I've downloaded emails by MS Outlook. TCPView stripped.
The TCPView stay clean until I've opened the Windows Mail.
Then tons of [SystemProcess]:0 appeared, most of them from port 12110 to localhost:high ports.
I set Stunnel for 11110 and not 121110.
I've closed Windows Mail. Open TCPView again, clean.
It's Windows Mail + Internet Mail provider, for sure.
If I ignore local communication of the Internet Mail provider, i.e., do not scan, open Windows Mail, I can receive email and TCPView is clean.
Something is different with Internet Mail provider & Comodo & Stunell & Vista.
