Samsung galaxy s5 downloaded a drive by attack file

A

AC Question

So my samsung downloaded a file when i went onto a site and im fairly sure its malware. I did not tap the file where it said download completed in the notifications and went into my files > downloads and deleted the file. I also went onto a computer and deleted it there too. I downloaded an antivirus app and it says im secure but i just want to make sure that i am safe if i didnt open the file and deleted it or if i have to do something else.
