No, I'm using Zone Alarm.  However, your answer and the ones at the link you provided have helped me resolve the issue.

The file in question in my case was commgr21.dll.  From the link I learned that this is the communication library for contacting Lacerte.

After updating and cleaning the apparent virus, I tried to get a REP authorization and the communication simply failed without any message.  Now it all makes sense.  Zone Alarm removed the file (I checked) and now I can't communicate with Lacerte until I reinstall it.

Thank you for your assistance and particularly the link you provided.

Stay safe.
