Microphone issues with Thinkpad

I am a regular Abobe connect user and had major problems today when leading a class.  Microphone is connected to computer, and shows up in microphone menu when I run the audio setup wizard, but when I press "record" to test it - nothing will record.  I tried this with 3 external mics (both USB and bluetooth) and no microphones would record.  They DID work for the speaker test, just not the microphone. 

3 minutes before my class launched, I finally found a second computer and logged on with that one - all the devises / microphones worked fine then.  

There is obviously an issue with my computer (Lenovo Thinkpad x1) or my internet security system (Kaspersky).  I have not changed any settings however since the class I led last week - which worked just fine! Any ideas of how I can resolve this?  I have class Day #2 tomorrow and it would be MUCH easier if I can use my main computer - the ThinkpadX1. 

Thanks in advance for any insight you can offer!
