Stupid Question I need To Ask

Hi Avast detected a suspicious file on my PC and a little bubble popped up notifying me of this, well that went away and I dont know how to access more information about the file that Avast detected. Any help is much appreciated, thank you.

:frowning:

assuming nothing else has popped up. Right Click thr Avast! Icon on the Tray > Show last pop-up message
