I would like to inquire if it is normal for all my internal and external hard drives to have $RECYCLE.BIN and System Volume Information? I did not notice them before it only appeared yesterday when I used my friends portable drive. Now all the external and  internal hard drives connected to my PC  suddenly have this $RECYCLE.BIN and System Volume Information.

Is it a virus? Cause whenever I delete the $RECYCLE.BIN it always comes back and I can not delete System Volume Information. I tried to format my external drives but it always comes back. Appreciate if you could help me identify if it is has a virus or not. Thank you very much.
