I've been using the free ZoneAlarm 4.5 with PC-cillin 2003 with
perfect coexistence so far even though I kept both of them updated with
the latest patches. A few days ago when my ZA's automatic update
checker announced a new security update, naturally I immediately
downloaded it for install. Apparently it was the ZA 5.0 update but the
install wizard refused to proceed unless I first uninstall PC-cillin
because ZA found it suddenly incompatible. Then I tried again the ZA
update install after I unloaded PC-cillin, but that was still not enough
for the ZA install wizard; apparently it recognized PC-cillin's presence
from the Registry, as you are suggesting. Now, I was not about to dump
PC-cillin I just re-subscribed for another year and I've been pretty
happy with. On the other hand I've been happy with ZA, too, until now
but I'm concerned that your method, though might get me through the
install hurdle, could still cause some incompatibilities down the line.
So for the time being I'm not upgrading my ZA 4.5 to 5.0 until this
issue is settled to my satisfaction or I find another firewall program
similar in capabilities to ZA and perhaps even free or at least
inexpensive. If anybody can suggest one, let's hear about it because I
am suspicious that ZoneLabs did this deliberately, using its entrenched
position in the firewall business to steal anti-virus customers for its
own new antivirus product. They must have taken a page from Microsoft's
strategy who also used its entrenched Windows OS position to sqeeze out
Netscape from the browser market and RealMedia from the streaming
audio/video market.
