Avast ???? suspicious msg

Hi, thanks for allowing me onto this forum.

Plugged my underwater camera into a public computer's USB port on an island in Thailand.

Next time I plugged it into my personal laptop/tablet, noticed a suspicious message - '???? hasn't yet opened' or something equivalent.

Immediately ran avast smart scan but it showed nothing. Now the cam doesn't work, laptop is slower and its avast has 6 new fields available to search for ????

(un)Surprisingly the search returns no infection results.

Pretty sure my android phone's infected too cos it runs avast. LoL not.
