AVG and Avast! coexist? (semi-long)

[Tom Geer]

I have been using AVG6 on a WinXP machine for several months now as my
primary resident, on-access and email AV scanner. As a secondary line
of defense I recently installed Avast! Home as my on-demand scanner.
I purposely did a custom install and did NOT install any of the
resident on-access components. Now when I boot up, I get an Avast!
error dialog box stating that it has found AVG6 resident components
and therefore has disabled all of the Avast! on-access, resident
components (which are not even installed!). Although I hate seeing
this dialog every time I boot, I suppose I could live with it. The
real problem is this:

After closing the above mentioned error dialog, Avast! appears in the
systray but with the red circle with a slash through it, no doubt due
to the resident components being disabled. When I double-click the
systray icon or right-click and select "Start Avast! I get the
following error dialog box:

"The AAVM subsytem detected and RPC error. The operation could not be
completed." And that's as far as it gets.

If instead, I double-click the regular desktop shortcut icon, Avast!
goes through its memory and startup scan and then promptly minimizes
to the taskbar where it can only be closed. It cannot be made to
appear on the screen normally.

The only way that I can get Avast! to do an actual scan is to select a
drive, folder, file, or group of files with Explorer and right-click
then use the context menu to scan from there. This does not show the
usual "skinnable" program display but rather just shows a plain-jane
rectangular box. I does, however seem to scan OK.

Has anyone gotten these two programs to coexist with AVG6 as the
primary resident scanner and Avast! as the secondary on-demand
scanner? I've done a fair amount of Googling and searching of the
Avast website but haven't found any definitive help.

Thanks in advance,

Tom

p.s. I had no such problems setting up this arrangement with Anti-Vir
as the secondary on-demand scanner.

I haven't done it (I use Avast as a primary and F-prot as a secondary)
but maybe instead of using Avast as the secondary, use it as a primary
(ie let it install normally) then use AVG as a secondary. Avast can be
weird working with other resident AVs- it doesn't play well with AVG or
Nortons, but a non resident scanner like F-prot gives it no problems.

It's my understanding that it is not a good idea to have two active AV's
such as AVG and Avast on the same system, even with one as an on-demand.
Although, some can co-exist well enough on some systems. There are some
users who have no problem with such an arrangement, but, they may also get
along well with their mother-on-law. ;-))

It is usually better to have an AV such as F-Prot as the backup on-demand
AV. There are others, but, I have not used them. Some Active run AV's can
tell when another is in the same domain, and they can't decided which is the
leader, or, each is determined to be King 'O The Hill, and it makes for
discontent or conflict in the realm. I myself use the F-Prot for DOS, as I
have WinME, I don't think the DOS works for XP, but, there is a version of
F-Prot that does.

Check here for more information on the F-Prot, or try a few other stand
alone types of programs. I'm sure others here will have their favorite to
share.

Ive had AVG6 and avast coexisting on a 98se pc , with avast as the resident
scanner.Disable resident shield in avg control centre and the avg stsrtup
(msconfig) entries.After a month or two and a bit of experementing i
realized that AVG detects less than avast so isnt really worth having as a
second opinion.Just use one of the online scanners as a second opinion and
choose one of the AVS to keep.Personally id choose avast.

I've installed both avg and avast on my father's xp system.
Other than avast's dialog box saying that some of it's
parts were disabled because of conflicts with avg,
it works just fine.

Maybe you should uninstall and re-install avast.
Also, I remember that during the avast install I
changed some options from their defaults.

I can't remember what I did now, but you could
try installing avast with different features
enabled than the default.

I've pretty much decided to not use AVG at all. When I downloaded
Avast, it wouldn't even install with AVG running. Once I cleared that
obstacle, it ran fine until after an update when it suddenly detected an
old copy of Nortons I had that came with the computer (subscription ran
out). From what I've noticed AVG and Avast are pretty heavy on
resources so one is enough (with F-prot as a backup)

Non-Win98 systems tend have unique problems, so you may have
to resort to the forum for assistance.

http://www.avast.com/forum/index.php?board=2

On my Win98SE, I need to ensure the msconfig|startup has only
one AV listed. Most AV's will automatically insert themselves
into the startup list. Even upgrading an AV will usually get
it listed again on the startup list so you must keep an eye
on them. My startup presently lists:

C:\Program Files\Alwil Software\Avast4\ashServ.exe

AVG, EZTrust and other AV's I have installed were removed from
the startup list. Each will still run on-demand.

I have tested each AV, one at a time, for their capabilities
to run in real-time without causing any problems or excessive
resource use. All checked out nicely as long as they are the
'only' AV shown on msconfig|startup.

Is this *really* because AVG detects less or is it because those files
that Avast finds to be infected it prohibits AVG from accessing? Have
*any* files found to be infected by Avast also been found by AVG?

If Avast would run was an on-demand scanner and not prohibit some other AV
product to be the resident scanner, perhaps it wouldn't *appear* to be as
good. (Then again, perhaps it could be *proven* to have better detection.
As long as it remains uncooperative, no user can tell for sure.)

I am now running AVAST and find it does a better job than AVG
especially with email. It does take more resources and slows some
things. It takes 13 seconds to load PhotoShop CS with Avast and 9sec
if I pause the standard shield. That is a huge difference. It doesn't
need to scan everything every time, but it does. I don't know if there
is a way to tell it not to scan certain files. If anyone knows I would
appreciate an answer.
