Application Error after updating to the latest 7.0.1456

Avast Free Antivirus / Premium Security
1

Hi,
After updating to the latest program version 7.0.1456 of avast Pro I get this msg…AvastEmUpdate.exe-Application Error
FYI…. XP SP3, no other security software and this was installed once over GUI update than on clean windows install with the same results.
When reverting to the privies version, error disappears.
Thank you

Reversion to an earlier version (you don’t say which version) could be that this element isn’t present.

This is usually a scheduled task and checks to see if there are any Emergency Updates, this is as its name suggests emergency use only, should there be a problem with avast that would otherwise require a clean reinstall to resolve can be pushed out to resolve it. It is also something that only avast can determine the nature of the emergency to formulate the update for release using this tool.

What happens if you run it manually, e.g. double click it C:\Program Files\AVAST Software\Avast\AvastEmUpdate.exe ?
You can also check if that file (and function) is present in that location with the versions that you installed.

What happens when you click Cancel (to debug the program)?
It would be nice to get a dump corresponding to the crash…
Thanks.

To the version 7.0.1451 prior to the version 7.0.1456

When running manually, there is no reaction from “AvastEmUpdate.exe”

Yes that file is in the installation folder, but as of function, well I’m not sure of function expectancy when double-click, again “no reaction” Thank you

The 7.0.1451 had a number of issues and that was why the 7.0.1456 version was released, so that would be the better option.

This would allow you to follow Igor’s suggestion and hopefully gather information which avast could analyse.

After double clicking [b]Avast\AvastEmUpdate.exe [/b]and not getting any reaction!! the error msg. has disappeared, so visually avast seem to be work fine, internally, well that’s something avast team has to determine I guess. Thank you I can reproduce the error by going back to my ISO created before double clicking AvastEmUpdate.exe and I still don't mind sending dump file, who/where do i send it to if you would like me to?

If you do have a memory dump from the moment the processed crashed (i.e. created at the moment the error message was shown), please upload it to
ftp://ftp.avast.com/incoming
Thanks.

Hi Vapor,

address 0x7c90100b contains ntdll!RtlEnterCriticalSection fnc code; since AvastEmUpdate module itself is not using critical sections at all, this problem is not easy to solve. Are you completely sure, that there is no other security solution which filters API calls?

Please use Dr. Watson to generate application crash dump:

  1. Register Dr. Watson as JIT debugger by command “drwtsn32.exe -i”
  2. Run drwtsn32.exe without parameters and select “Full” crash dump type in Dr. Watson’s dialog.
  3. After next crash of AvastEmUpdate.exe, please submit crash dump to ftp.avast.com “Incoming” folder, default path of crash dump file is C:\Documents and Settings\All Users\Application Data\Microsoft\Dr Watson\user.dmp

Thanks

Well that’s where I’m a bit of fault, my apology. What i have missed to mention that I do run Outpost Firewall Pro and I did check if there could have been filtering blockade, I discover that outpost was blocking AvastEmUpdate, it wouldn’t even pop the warning about it. By double clicking the AvastEmUpdate outpost would create a rule of allowance and problem was gone, and no I`ve never had to put avast for outpost exclusion, never had any issues.
But I do have a question how exactly emergency update benefits us, is there detail description I can read about. Just like with all the extras avast has added to its software (safe zone, sandbox.ext.) I don’t use it so I’m wonder if I would even want that function to start with my windows.
Thank you

Hi Vapor,

AvastEmUpdate is just backup update way, used only if primary update way fails from some reason. It is intended only for internal Avast usage. Standard windows scheduler is used to execute this app once per 12 hours. Also do not worry about system resources, because it runs with idle priority. Only thing this tool do is simple check on avast servers to determine if there is an emergency update available or not.
