I've noticed recently that whenever Avast updates its definitions its trying to run a series of large unprouncable .exe file names (such as a series of random letters and numbers). Is this something Avast has always done and are these just temp definition update packs or something? All the tests I've done so far are not reporting a problem so I'm guessing its ok but just looking for some confirmation.

Hi neko -

Do you run Version 8 of avast! and what Firewall do you run ?


I checked several similar questions on avast forum recently and this is a copy of one post on avast! forum in relation to recent updates over the last few months :


Question =

Online Armor questioned about 3 weird .exe files like :
92d1d255-f490-4c4a-90ca-1e19926aea5f.exe,, (
C:\Windows\TEMP\92d1d255-f490-4c4a-90ca-1e19926aea5f.exe  Hash(MD5): D10A35D060D7164FFFE2CD7195EEA2DF
This happened after I upgraded to V 8. 

I opened file location and I saw one of them was in the Avast directory.


Reply =

The general reply was "not to worry" about these in updates.


Thank You -

Hi, yes av8. Thanks for the help, seems strange they wouldn't have given more of a notification about it. I guess its ok to allow the updater to do its thing and forget about it?

My understanding from info posted at that avast forums is that those long alpha-numerical file names are related to avast Emergency Update Checker which creates them in a temp folder when checking to see if there is an emergency update present. This feature (introduced in v7) allows avast to roll out updates in the event there is an issue where the avast service is not able to state.
