Zonealarm warning

[Dennis Powless]

I think it's fair to turn off anti virus programs and firewalls when
installing a program.  But, turn the right back on.  This goes for
known programs, not ones your not sure about.  I frequently see this
as 'solutions' for failed installs of all kinds of programs.
