I want to install Eset's NOD 32 trial version. It Warns me to uninstall
any resident anti-malware, in order "to avoid serious problems during
installation."

Questions:

A) what problems? IMO, there should be no problems at all - unless NOD32
immediately activates itself after installation, which it should _not_
do. No program should do _anything_ until you start it.

B) If I do uninstall, based on your advice, is it OK to re-install
afterwards? (Avira, Malware Bytes.) These programs didn't insist on
uninstalling competitors, so it should be OK to reinstall them, right?

Thanks for your advice.

To be effective, an on access AV scanner wants to be first in line for
setting its hooks in the system. Other types of resident antimalware
modules might interfere with installation information (registry?) by
restoring them back and borking the installation.

If the installation file from Nod32 has not been "infected", then why
not trust them and remove the resident AM program for the duration of
the installation process?

That depends on what constitutes "installation". Some AV programs need
to start running before the user even has an input console to
communicate his wishes with.

Avira, no. MBAM, yes. Avira might co-exist if it could be configured to
be used as an on-demand scanner.

Have you asked their support techs? It looks to me like they just wanted
the "resident" antimalware stopped, not necessarily to uninstall the
entire application permanently.

Of course any AV-program will start working immediately after
installation, that is the purpose of the program.
Why would you expect otherwise?

Why not?
Malwarebytes is *not* an AV-program.
Avira also warns during installation, that another av-program is present
and *may* cause conflicts.

So I installed NOD32 first and installed Avira second (disabling Avira
Guard).

Well, Fred, I think that the purpose of any program is to do what I want
it to do when I tell it to do so. The install should end with a Start
Program Now? request for permission. And if an AV program has a Guard
function, the first thing it should ask is whether to turn that function
on or not. It should never turn that function on by default, precisely
because doing so might mess up what's already installed and running.

Anyhow, I want to test NOD32. That means I want to know about its scan
and clean function above all else. So starting its guard function would
be, erm, annoying.

See above.

Thanks, that's very useful info.

Yeah, but I don't want to remove any of 'em. I want to have the one with
the smallest footprint run in the background on boot, and I want to run
scans with a bunch of others from time to time on demand -- with no
mutual interference. I don't think that's too much to ask.

There's a regrettable and growing tendency for makers of anti-malware
software to want to The Only One.

cheers,

Wolf,

I agree with you on most of your issues. NOD32 had a "Quit" feature that
allows you to easily disable the program. You can access it through the
"tray" icon. It will restart at the next boot or you can restart it by
clicking on the NOD32 icon.

Chas.
