Drives E:, F:, H: - what are they, USB flashdrive keys? Whatever, check them for Autorun.inf files. Those files possibly contain something like...
...where LG.ico or similar is pointing to an icon file somewhere.
Just delete the Autorun.inf files.
The only possibility is, you have installed any LG driver or software application whose installation files are copied into these drives. There would be an autorun file in these drives and you need to delete these autorun files applying that LG logo to these drives.
