Title: Lots of tmp files in Users/(myid)/AppData/Local/Temp
Post by: YeOldeBowler on January 15, 2019, 07:02:33 PM
The following has been happening since updating to 19.1.2360 (build 19.1.4142.0):
On start up I get 165 files in the above folder, all approx 1.5 mb in size (total of 254 mb).
I also get two tmp-shm files on every start up. These are not deleted on restart so the folder is growing and growing.
Can anyone please explain what they are, why they are there and how I can stop them  being created.
I assume I can delete them without a problem.

Thank you

Edit: the file format is 'prbxxxx.tmp' (where x = ?)

I suggest you do a Clean Install of Avast:

Thankyou bob3160. Unfortunately I still get the tmp files after doing the clean install.
Any other ideas please ?

New ones or are they the original temp files ???

I am getting new ones and the previous ones are still there.
I have now successfully stopped this happening with the prbxxxx.tmp files but am still getting the tmp-shm files (which are being added two at a time with the old ones still there).
To stop this happening I went to the add/modify components section and removed the components shown in the attached screen print.

Hi YeOldeBowler,
would you make a procmon log and upload it for analysis ?

1) Disable avast self defense
2) Download procmon from https://docs.microsoft.com/en-us/sysinternals/downloads/procmon
unzip and start the procmon.exe as admin
3) When there will be a new prbxxxx.tmp file save procmon log. Menu -> File ->  Save.. -> check all events, check native procmon format and select path where you want to save a procmon log.
4) Pack the procmon log as yeoldebowler_1_2019.zip and upload it to ftp://ftp.avast.com/incoming
5) Enable avast self defense

Thank you for report !

I reinstated the options, rebooted but the problem did not reappear.
I then did another clean reinstall, as outlined above, and the problem was back.
I ran procmon as suggested but it was over 3 Gb so I filtered it to show only prb and tmp-shm.
I have zip'd the file but am unsure how to FTP it to the address given so I have attached it to this post (please note I have changed the extension from zip to txt).

Hopefully it will shed some light on the problem although I will do as above (turn off certain options) to stop the build up of files (256 mb per startup).

Please let me know the outcome and also if I can assist with anything.

For what it is worth, I too seem to be getting the same effect on my Win10 (1809, 64 bit) system.

It is not at all clear what event creates the files as (from the time stamps) they seem to appear in batches - I have 25 with the same time stamp, each 1579 kb - and the batches seem to appear once or twice a day, not regularly throughout the day as (for example) vps streaming updates are picked up.

I don't know whether they are from Avast or not, but I didn't see them before updating to 19.1.2360. The names are of the form prbE6D6.tmp with the 4 capitals/numbers changing.

The positive is that ccleaner (mostly) removes them.

Michael529 - It may be worthwhile trying my fix in Reply #4 (in Troubleshooting). As I mentioned in #6 I reinstated them and the 'rogue' files stopped.
This is only a stopgap (if it works for you) until a proper fix is made. From my research it seems that the Avast service is creating them...

YeOldeBowler, thanks for the log.
It gives some hints, though the stacks are incomplete... did you disable Avast self-defense before running ProcMon?

Just to be clear - were both the prbXXXX.tmp and appXXXX.tmp-shm files left behind? It may be two unrelated things actually.

Yes. It will give Igor more of the information needed to get to the bottom of what's causing this.
Title: Re: Lots of tmp files in Users/(myid)/AppData/Local/Temp
Post by: igor on January 16, 2019, 11:38:08 PM
If possible, yes please... it would show us where (i.e. from what piece of code) the files are actually created without subsequent removal. (The filter for prb and tmp-shm only is fine.)
Title: Re: Lots of tmp files in Users/(myid)/AppData/Local/Temp
Post by: YeOldeBowler on January 17, 2019, 05:53:04 PM
Sorry for the delay - have to do a clean reinstall first to get the problem back.
Have ftp'd yeoldebowler_2_2019 (with self defense off !)
Hope it helps.

Hi YeOldeBowler,
prbXXXX.tmp files are related to data scan component. Issue reported to responsible devs. 
thank you for logs !

Working together to solve a problem.
I'd call that a strike. If we get enough of them, we'll wind up with a perfect game and a perfect Avast. :)

Hi,
the fix will be released in  19.2 version which will come soon. (It is already available in beta)

For information only:
Have not had any *.tmp-shm files since 11th January - not sure what has changed (last prog update was on 3rd January).

The fix was probably accomplished via a VPS update.

Well, i have same problem too, prbxxx.tmp files keep appearing after i restart my laptop.
every restart always around 800mb to 1 GB space taken in Appdata/Local/Temp folder

i have to take kaspersky as replacement now, use avast from 2010, this problem make my hardisk full.
hope this problem will be clear.

Hi Gufron,
if you still have the same problem please provide us procmon log for analysis.
In comments above you will find step by step description how to create the log and send it to avast ftp server.

Hi Kwiq

Can we be clear please whether there was a program update (Bob3160 suggests it could have been by VPS) or whether the fix is waiting for version 19.2? Certainly the prbxxxx.tmp files are still appearing here, without any pattern of time or activity that I can see. So: did my system miss a program update (possible as I don't reboot very often)? Or is there no fix for 19.1?
Title: Re: Lots of tmp files in Users/(myid)/AppData/Local/Temp
Post by: igor on January 30, 2019, 12:31:28 PM
The app* files have been handled via VPS, but prb* files require a program update.
A fix will be included in 19.2, there's no update for 19.1.

Dont have time to do that pal. need extra time to do that and prbxxx.tmp files created after 1 or 2 days not appear right away after installed.
Clean install avast, download from the web, created new user account, refresh windows, reinstall windows.
man, enough about that. 9 years i used avast, never once i experience this problem.

Run CCLEANER daily until the fix in 19.2 to stop the creation of the prbxxxx.tmp files appears?

Will the update remove the prb tmp files ? I volunteer with a silver surfers club and have been getting people to use Avast. Unfortunately a lot of the members will not know how to remove the tmp files. I can, of course, create a simple batch file or use CCleaner but would 'prefer' if the update did it automatically.
Thanks
