On my desktop Windows 10 system I run AVG Free virus detection. The AVG software claimed that it had just updated. Very quickly it complained about a threat named IDP.ALEXA.51 located in the LogosIndexer.exe. Soon after it reported a threat named "General behavorial detection" in Logos.exe. Both were disabled and I am now reinstalling my Logos 6.
Windows file explorer reported that both the Logos programs were last updated in September.
If this happens again I am going to get rid of AVG. I have never had problems like this before.
