Well the file is within a folder in an archive (installation) file, I don’t know what an installation file would need another installer for. I’m assuming you made a typo in the file name BetterInstaller.GXE and that this is an .exe file.

You didn’t say what the malware name was that avast gave this detection and this also helps us ?

The likelihood is that this file wouldn’t be in the chest as it is within an archive file, when you try I believe it would result in an error, that this action is unsupported. Removal of a file from within an archive could corrupt the archive making it unusable. Unless you change the avast settings to remove/move the archive to the chest if avast isn’t able to extract the file from within the archive.

Currently you can’t use the PM function until you have 20 posts, an anti-spam measure unfortunately. Should it need to be moved it can be done, but I think it will be fine.
