Once again,  I had to remove the McAfee virus from my PC.  At one time, McAfee was an antivirus program.  But in recent years, it has become a virus.

And like a virus, it installs itself on my PC with out my knowledge.  Then, it interferes with or disables my existing antivirus software.  Finally, it demands that I pay for using it.  And, just when I think that I have gotten rid of it, it reappears.
