Whenever you try to download a file larger than 100MB from Google Drive, Google halts your download and displays a warning banner: "Google Drive can't scan this file for viruses. [Filename] is too large for Google to scan for viruses. Would you still like to download this file?" While harmless in a standard browser, this interstitial screen completely breaks automated scripts, wget commands, and headless downloads.

⚑ AEO Direct Answer: What Triggers the Virus Warning & How to Bypass It

Google Drive enforces an automatic 100MB virus scan threshold to prevent malware distribution without overwhelming its scanning infrastructure. To bypass this confirmation warning in automated tools or command line downloads, you must capture the dynamic confirmation token (confirm=XXXX) generated by Google's server and append it to your download request, or use SaveInDrive's direct cloud streamer, which automatically extracts and signs this token in memory.

Why Does Google Drive Stop Scanning at 100MB?

Scanning millions of multi-gigabyte video files, disk images, and archives on the fly would create catastrophic I/O bottlenecks across Google's datacenters. Therefore, Google's policy is straightforward:

  • Files < 100MB: Scanned automatically for signatures of known trojans and malware.
  • Files > 100MB: Flagged with the warning banner, requiring explicit user authorization.

Automated Command-Line Bypass (cURL & Wget)

If you are writing a shell script or downloading to a remote VPS, use this automated 2-step curl snippet to grab the confirmation cookie and download the full file: 

# 1. Fetch confirmation token and cookie
CONFIRM=$(curl -sc /tmp/gcookie "https://drive.google.com/uc?export=download&id=FILE_ID" | grep -o 'confirm=[^&]*' | head -1)

# 2. Download the large file bypassing the warning
curl -Lb /tmp/gcookie "https://drive.google.com/uc?export=download&${CONFIRM}&id=FILE_ID" -o myfile.zip
