Just don't get too comfortable with any single product. I don't want
to get off on another Symantec rant. But I thought it was a good
product. I've seen it miss viruses in Outlook Pst modules. It also
doesn't seem to catch some of the Java cache pests as well. Even
though I've moved to eTrust, I still run some of the other vendor on
line scans to double-check.
Recently, I've migrated a number of customers to eTrust or even
AVG/AVast for cost reasons and in many of those cases the first full
system scans found infections that NAV did not.
As to McAfee - I worked in an Enterprise where McAfee was the
Antivirus software. It was a nightmare. The only AntiVirus software I
ever saw that created more issues than it ever solved.
No matter what you use, I would recommend taking 30 minutes or
so to run both Panda & TrendMicro's on line scans. You might be
surprised at your results.

I guess the point of all this to point out that product allegiance is O.K,
up to a point. Never assume that Good Ole 'Fill-in-the-Blank' is your
best choice/option.
