Thanks, I really wasn't expecting answer. I made the post to help others who may encounter the same problem
Nonetheless, following are the answers to your questions
I have a cable connection to the Internet
I also have McAfee Security Scan Plus. This was installed unintentionally -- I guess that I failed to uncheck an option to download it when installing something else. In the past I've had BitDefender and Norton Antivirus Corporate Edition
Maybe this has changed since I had the problem on July 4, but the versions you asked about are

Virus scan : 15.0.291 Build 15.0.291 Last update 7/21
