Hello Readers; Further to my postings of yesterday, I have identified a temporary workaround to the issue of have KIS blocking your You Tube uploads. This will not work for everyone sadly. I transferred my rendered video mp4 files to my Samsung tablet via bluetooth. I uploaded to my channel directly from my tablet - which incidentally is also protected with Kaspersky. Clearly the Kaspersky product protecting my Android tablet is a very different product than that protecting my Win10 laptop and it does not block uploads to You Tube at this time. This workaround is a nuisance and requires extra steps and considerably more time, but it works.
