Should I exclude the TEMP folder from scanning?

Avast Free Antivirus / Premium Security
1

One of the programs I use daily gets a sharing violation and loses info when one of its files that it created in the TEMP folder gets locked by Avast. Their support people say that I need to exclude the TEMP folder so this won’t happen again. I think it would be a bad idea.

Thoughts?

Well, any exclusion is more or less dangerous (depending on how exactly the mask is set, for example).

However, as far as I know, Avast scanning should be synchronous - i.e. there shouldn’t be any sharing violation, the calling process is simply stopped and waiting for the scanning to finish (unless some strange multi-threaded processing takes place). Can you tell us more about the problem - i.e. what program is that, how to reproduce the issue etc.?
Thanks.

Seems nonsense. At my computers TEMP ist not excluded, and I have no such problem.

Sorry for my English.

Same problem here, Windows XP Sp 3
In my case it happens with:

  • 7Zip when I drag and drop files (7Zip creates a temp folder - inside system temp folder containing extracting files; while when I use “Extract…” menu voice, the temp folder seems not to be created and so there’s no problem)

  • Thunerbird not always, when a file ends up in “Moz_mapi” temp folder

  • Copernic Desktop Search 4.0: it writes some dll files in the temp folder
    • at startup: Copernic says it can’t read the config file (which isn’t in temp folder)and crashes
    • when opening the option window and it crashes again

Tried to set Avast not to use the Cache, and sometimes it works.

Now I’ve added a “write” esclusion for Temp folder and everything seems working

Cheers

I wouldn’t say anything until I know more about the file.
With all due respect, your system is “not” exactly the same as the OP’s set-up.
It’s always best to get as much information as possible before making such a comment.

@Giannux Please start your own topic. It’s extremely difficult to help two different users
at the same time. Even more so because set-ups vary from user to user.

In this case I would check the file in the TEMP folder that gets locked with Avast.
