Google-drive – Save to Google Drive

More than likely this was functionality that Google was rolling out gradually and your co-worker simply hadn't gotten it yet. This is very typical of how Google implements new functions, I expect so that they can halt the deployment if it's found to have an egregious bug and minimize the damage.

Generally, the only thing that can be done is to wait for the rollout to complete.

A cookie must match the "confirm" url parameter, and it is changed on each call.

Here's a perl script to download these files in an unattended way.

With the url from the antivirus scan warning page (https://drive.google.com/uc?export=download&confirm=s5vl&id=XXX) this code should be enough:

#!/usr/bin/perl
use strict;
my $TEMP='/tmp';my $COMMAND;my $confirm;
sub execute_command();
my $URL=shift;my $FILENAME=shift;
$FILENAME='gdown' if $FILENAME eq '';
execute_command();
if (-s $FILENAME < 100000) { # only if file isn't the download yet
    open fFILENAME, '<', $FILENAME;
    foreach (<fFILENAME>) {
        if (/confirm=([^;&]+)/) {
            $confirm=$1; last;   }    }
    close fFILENAME;
    $URL=~s/confirm=([^;&]+)/confirm=$confirm/;
    execute_command();    }
sub execute_command() {
    $COMMAND="wget --no-check-certificate --load-cookie $TEMP/cookie.txt --save-cookie $TEMP/cookie.txt \"$URL\"";
    $COMMAND.=" -O \"$FILENAME\"" if $FILENAME ne '';
    `$COMMAND`; return 1;    }
