Dreamweaver sync trojan?

An Avast trojan alert message popped up when I tried to synchronise my website yesterday, gupygapyg.html appeared but disappeared soon after. JS:Redirector-WF [trj]
Did Avast delete it? Any clues. Puzzled.
Thanks.

have you restarted since it happend?
if not, right click tray icon and “show last popup” click the pin in top right corner to make it stay on screen
take screens shot and attach it here

have you checked avast chest/quarantine…any bugs there?

Just checked and it’s in the Virus chest.
