Yesterday I downloaded and attempted to install the newest version of the Community Edition of IRIS but not the preview, and attempted to update an older version, but each time I tried to install it, I would get an error, and then an antivirus program would indicate that it had identified and blocked a threat (McAfee identified it as GenericRXAA-FA!EAEEF9B8457F with a location of C:\Users\jivey\AppData\Local\Temp\pbt3FDD840C\IRIS_x64.msi).  I tried the installation again this morning and this time a threat was identified by Malwarebytes as Malware.AI.
