One Antivirus Rule
Styxx2
Some may disagree with this and some will take heed, as expected, and
welcome others' opinions are. However, the post needs to be made.
Actually, with the DOS Rescue /Reference disk(s) that all Antivirus
Programs come with and suggest you create after your initial update of your
AV Program, you actually have two (2) AV scanners available with each
Windows AV package. So a second Windows AV Program and its Rescue/Reference
disk(s) would be like having four (4) AV Programs not just two.
The Anti-Virus/Security community does not recommend running two
Antivirus programs at once on the same machine, but some users do make
unfounded dangerous claims to use two or more Antivirus Products (AVPs) at
once without problem. For safety reasons, I use one (1). Never use Mcaffee
or Norton Antivirus in combination with each other or in combination with
any other antivirus program.
When uninstalling any software Never remove/delete a Shared Component if
prompted. Always choose 'No to All', 'Keep' or 'Remove None'.

You see, you can't be sure that any single product will counter all
threats or be running flawlessly all the time, so a multi-layered defense
can increase your security: One protective technology can backstop another.
But there's a big "if:" Multiple layers of defense are better than single
layers *IF* they don't interfere with each other. In the case of external
routers, servers, NATs, firewalls, etc., they'll rarely interfere with those
that reside locally on your own PC: Because they can coexist well, they can
work together to provide more security than either could alone. But if you
add multiple firewalls, intrusion monitors, etc., on the *same* PC, you can
run into trouble because the apps compete to "own" the processes they're
designed to monitor. Antivirus tools work the same way: External,
centrally-installed server-based antivirus tools can coexist well with
locally-installed, PC-based AV tools: They can buttress each other. But you
usually CANNOT install multiple AV tools on the same PC: They end up
stepping on each other's toes and interfering with each other. So there's no
single Yes or No answer to this: It's conditional, based on whether or not
the additional products can work without interference. If they can coexist,
then the extra security is a good thing. (By the way: Long-time readers may
recall that we've previously covered how to add multi-layered,
non-interfering defenses to your PC's online setup, making it all but immune
to external threats.
