After trying any kind of solution available regarding this particular error 0x8 (in windows xp), nothing was able to solve this error. Namely,
IRPStackSize registry entry modification (

PoolUsageMaximum and PagedPoolSize registry entries modification (
https://support.microsoft.com/en-us/kb/304101) (Still same Error)
I also added Ram to several clients (Still Same error).
Moreover in several cases the VPSUPD.exe cannot be executed successfully generating a “You are already up to date” popup box (yet, you have very old defs)
In either case, the problem reappears every 1-2 days, making it very difficult to manage the updated VPSUPD.exe distribution and installation on the clients.
From my point of view, the error occurs while incremental update of vps_32-XXXX.vpx definitions file is executed; using the small frequent updates vps_32-XXXX-XXXX.vpx.
For some reason the “old definitions file” (vps_32-XXXX.vpx), which is already huge ~250MB, cannot be updated/appending the latest definitions.
After many attempts, I use the following solutions is the following,
- 1) Before proceeding, using the AEA console, I disable the Self-Defense module of my XP Computers Group (Located in the Troubleshooting Tab)
2) I create a script that deletes the old VPS_32-XXXX.vpx file located in the %programfiles%\AVAST Software\Avast Business\Setup\
This script can be executed either on your clients using a logon script or a Registry entry, or on the server using the administrative shares of the clients \\Client\c$\%programfiles%\AVAST Software\Avast Business\Setup\
3) After deleting, every client will be forced to download the fresh-full VPS_32-XXXX.vpx file through mirror and update AVAST with the latest definitions.
4) Last, I check that every client has the latest definition and re-enable the defense module of my Computer Group.
I know that the above mentioned procedure is a waste of bandwidth and might not worth for a small Lan, but in case of several remote sites or large Lan, it is very simple and quick for daily usage.
Hope to have an AVAST program update very soon.
