PDF:UrlMal-inf [Trj]

My Avast file system shield has blocked a trojan infected file, PDF:UrlMal [TRJ], residing in my Dropbox. I have deleted the listed PDF file on my Mac and on my Dropbox on-line. Still getting the Avast pop-up that the infection is still there and it continues to block and isolate the same referenced PDF file name. Can anyone tell me how I can remove this trojan from my Mac? Thank you. --Aswift

Try clear your dropbox sync cache and reboot your Mac >> https://www.dropbox.com/help/desktop-web/cache-folder

Any change?

Yes, looks like it worked. Thank you very much.
