All that aside, using existing patches and NOT using software with known
vulns such as IE. There are unfortunately a select few sites where IE is
required. Those are dwindling, and more importantly can usually be
avoided altogether.
The sad part is, I *have* to keep a functional current version of IE on
the system, if only for testing reasons. It would be nice if there was a
very simple way to disable its integrated functions easily when not in use.

Of course. Many of the stock Windows components are removed or replaced.
Notepad is a classic example, replaced by Textpad. Cygwin (with a lower
case "w", ahem) is used for its toys and cross training. Putty for
Telnet, stuff like that.

PivX's original list (or its content) lives on, just in a different
location.

Again, of course. It has a properly tweaked httpd.conf, and while I do
keep a cgi-bin directory accessible and readable it has nothing of
consequence in it. More of a nose-tweak if anything.

HTML rendering is disabled, as well as remote images. Pop-ups are toast,
and images only loaded from orig server in browsing. Bayesian Junk
filters enabled and well trained.

Perhaps, but they're annoying as hell. It's a risk I'll accept. As a
single user machine it has outbound connections manually monitored, and
no (known) rogue software.

Why? SA runs on the (remote) mail server, stripping all executables and
classic MS hangers on (scr, com, bat, etc....) as well as tagging Virus
and filtering those in Moz.

F-Prot, and others tried.

Ad-aware run *very* occasionally. Executable binaries almost always go
through MD5 checksum vetting before install. No browser plug-ins allowed.

I keep a copy of Knoppix handy and updated. I may try out something else
soon.
Thanks... gives me something more to chew on.
Obviously, this is FAR from your average Windows users box. I'm quite
aware of threats and have even discovered a few myself.
Our resident Grandma posting made *me* realize that not having to
reformat often (because of this same awareness, never) is a good thing.
