Hello Jim,
The problem you're encountering is not because Google Drive is installed on your PC, it's because the file you're trying to download is stored in Google Drive. Once a file exceeds a certain size, Google Drive can't scan it for viruses and gives you the warning message you're seeing. The fact that the file you're receiving is garbage suggests there may be issues with how the file is being downloaded or with the file itself. Here's what you can do:
1. **Use a Different Browser**: Try downloading the file using a different browser. Some users reported this solved their issue.
2. **Disable Browser Extension**: If you have any browser extensions relating to downloads, disable them for the duration of the download.
3. **Contact the File Owner**: If you know the person who uploaded the file, it would be helpful to contact them. They could try to compress the file or split it into multiple parts before uploading it again.
As for Google Drive not being installed on your PC, you're correct. It seems you're interacting with Google Drive on a web interface, so you don't have to uninstall or remove anything on your computer. In this case, Google Drive is acting as the conduit for the download, not as an installed program on your PC.
