Restricted Users can't run !Avast (Managed)

I have installed ADNM and all seems to be working well except with regard to Restricted Users.

I have remotly installed the !Avast NetClient, and in all cases the On-Access scanner works fine.

But when a WinXP Restricted User (Users Group) tries to run !Avast (Managed) from the Start Menu I get a series of errors.

“Unknown error.” “avast Splash Screen” cannot load configuration.

“Unknown error.” “avast Simple User Interface” cannot load configuration.

Then nothing. No Avast for manual scanning.

It seems like a permission issue, because if I run avast (managed) as Administrator the all works as it should.

Thanks,

I’ve also noticed that if I right click a file and click “Scan” as a Restricted User, I get this error.

“Program cannot load Storage.”
“Error: Unknown error.”

I’m not sure how this avast! Distributed Network Manager version works.
But in avast! for PC, storage errors could be solved changing avast4.ini file, [Common] section, item Database=ODBC to Database=XML.
This prevents the Microsoft Jet drivers from accessing the database (storage). ::slight_smile:

Is that something I would have to do for every user on every workstation?

That would take a very long time…

LedHed, I’m not an expert here, you can test or you can wait for the programmers. Sorry ::slight_smile:

Is this the latest build of the NetClient?
Can you please check the access rights for the file \data\avast4.mdb?

Thanks

NetClient V. 4.6.348

Avast4.mdb

Everyone = Read/Write
Users=Read/Read&Execute
PowerUsers=Modify/Read&Execute/Read/Write

Note: Power Users have no problems running Avast (Managed)

I did a little tweaking of the permissions on the .\Avasr4\Data directory and if I grant Write permission to Users then it works fine.

I tried granting Write permission to just the Avast4.mdb file but that didnt resolve the issue. So there must me a few other files in the DATA directory that “Restricted Users” need write permission to in order for Avast to run.

-LedHed

I should have put all this in 1 post, but too late for that now.

Any how.

These files need Read&Execute, Read, Write permission for the “Restricted Users” or “Users” group to run Avast (Managed).

Avast4.mdb
License.dat

Is there an easy way to make these changes for all 30+ users on my network? Can it be done as a ADNM Task?

Hi, I’m new to the world of avast so any help would be greatly appreciated!

I’m having the same problems which ledhed documented some time ago. I’m using ADNM to distribute Net Client to a number of PCs on a small LAN. I’m having no trouble with ADNM or logging on as a administrator to a network machine and installing the Net Client software. The problem exists when I try to open the avast antivirus(managed) on the network machine as a limited user (Users group), it will not open, giving me the same error message ledhed quoted in the original post -

“Unknown error - avast splash screen cannot load configuration”

&

“Unknown error - avast simple user interface cannot load configuration”

I have no problem running the software under an administrator account. Also the virus scanner is running under boths types of account, its just I cant open the software to do a system scan.

Anyway, I tried changing the permissions on the Avast4/DATA folder/files like ledhed did but this has not worked for me!

Below are the specs of what I’m working with -

Windows XP SP2
ADNM 4.6.453
avast netclient 4.6.476

Any help would be greatly appreciated!

Thanks

Is that problem still exist ? even with the latest netclient releases ?

I am experiencing the same issue and it not really convenient to change the permissions manually on all client machines…

vlk, could you please update.

Many thanks

This should not be an issue already…
Are you guys using the latest version of netclient (4.7.652)?

Thanks
Vlk

hi,
Yes this is the version I have…

And the operating system is XP?
And everything’s working OK if the users has admin rights?

Thanks
Vlk

yes correct.

Same problem here!

But not Avast4.mdb, here Avast4.db!

ADNM 4.7.608
avast! NetClient Edition 4.7.652.0

Windows XP SP2 on all Clients

Has an admin EVER logged on this machine after avast installation? Could you please try logging on as admin and the again as non-admin if that makes any difference?

Thanks
Vlk

Hello,

no difference!

Can you please check the access rights for the file \data\avast4.db?

With GPO.

But it’s not a good solution to give Users write permission!
