I suggest a search for RPC error in avast! foruns.
Lots of foruns have discussed this in the past.
Like Vlk, version 4.1.280 must work ok with them.
Are the RPC service starting automatically with the OS?
What firewall and spyware were installed?

Hum, I did search for “rpc error” before I posted; no results were returned.
I did not know RPC was a separate service; I’ll check if it is being started as soon as I get back to that computer.
I’m not using any firewall/spyware software (however, ZoneAlarm has been recently uninstalled on that computer).
Thanks for the quick reply. I’ll post as soon as I have details.

Well, I checked and the RPC service is running. Another service, called “RPC Locator” was not started, but starting it does not make any difference. I still get the same error.

Chriz
I don’t have an English OS so I cannot find the specific service RPC Locator (I suppose it is the Alocator Remote Procedure Call and manages the data base names RPC) :
I suggest you open the properties of the “normal” RPC service and see if avast! is named as a dependent service (i.e., if avast is listed at the dependent services of RPC).
Maybe another test, try to reinstall ZoneAlarm and see if this correct the error. I have ZA too and everything is working fine with avast.

Hey Guys,
I am having the same start up problem as Chris has - The RPC unable to start up issue…Adding to that error message, I also receive a message from Visual C++ library about runtime error shut down request… Any updares on fixes?
Are you guys having or had this problem b4?
Also Any solution yet???
Please post a response to my questions soon for I am not quite sure if avast is protecting my pc at this time…???

Chriz, RPC is Remote Procedure Call.
There are various configurations mentioned at http://www.blkviper.com/WinXP/servicecfg.htm to shutting down and disabling many of Microsoft’s services which you may do not need. But
these actions - disabling Windows Services - is quite an advanced task. Avast! requires at least RPC service running… You can cause more conflits doing so. Be smart! Good luck. If you need more help, tell us.
Try to desinstall, boot and install avast again.
If this not work, please see Administrative Tools / Services
and look what is marked to RPC Service. It must be Start Automatically.
Both avast Services must be setted to start automacatilly either…
Btw, RPC is indeed an independent service of NT/XP systems. Just search the word ‘RPC’ in forums, you´ll get some:
This forum includes ZoneAlarm and RPC discussion
This forum includes a picture of RPC Window
This is specific of RPC error

Issue of “the AAVM subsystem detected a RPC error” is related to the logon failure of the current user accounts .Check the avast antivirus service in service section and go to LOGON TAB and browse for the appropraite user accout . Enjoy …

In fact, avast must logon as LOCAL SYSTEM and must be allowed to interact with the desktop

Hi there…
I just installed the latest version on W/98 but i get the message:
AAVM - initialization error: AavmStart: avworkInitialize failed, 0000007B
i de/reinstalled avast a few times but still no change… how can you help me?
thnx a lot…
JayFK
Do you use any other antivirus in your computer?
Did you use in the past?
Do you have a firewall or other security program installed?
Please, search the board for avworkInitialize and see if you get any solution for your problem…
A reinstallation should done but I’ve tried and nothing…
