I tried replacing the file that McAfee recommended and, while it did
help to speed up my system, it was still noticeably slower with VShield
running - especially when using Internet Explorer.  The most noticeable
problem was that while a page was loading, if I moved the mouse, it
would move across the screen with many jerks, not smooth at all.  I had
a couple of extra copies of Norton Anti-Virus left over from an install
so I put one of them on.  It is quite an improvement - not nearly as
intrusive when the automatic scanner is running.

One thing difference between both Norton and VirusScan 4 and VirusScan 5
is the addition in VirusScan 5 of many more file types.  If you look in
the list of file types being scanned by VirusScan 5, you will see many
Internet file types like HTM and many that I've never heard of.  These
are not present in either Norton or in VirusScan 4.  I wonder if this is
what is causing the slowdown, especially when using Internet Explorer.
