We have a web site that makes several PDFs available for download. The PDFs might be static, or dynamically generated. They are downloaded using one of several mechanisms (static-URL, post back/redirect/meta-refresh/etc.). For certain PDF files, Chrome downloads them without complaint. For others, it warns the user that "This type of file can harm your computer. Are you sure you want to download ..." and requires an extra click.
IntroAt first tested opening the PDF in the Console.I also tried a timeout which didn't help, but it did give me a msg the 1st time (This site is attempting to download multiple files. Do you want to allow this?).

The server returns the wrong content type for the file (i.e. "test/html" instead of "application/x-pdf"). Some hacked sites try to send you screen blankers (*.scr) telling you "this is pr0n! Open it right now!". Double clicking the file will install a virus on your computer.
The file contains various file extensions. Just hexedit the file and remove the extension you want chrome to ignore. e.g. I wanted to download *.mat files, so I searched for 'mat' and replaced it with 'xxx'
You can disable this feature through the Advanced Settings option in Chrome Settings. (Please see the screenshot below.) Unfortunately, it's not very granular because disabling it also disables other safe browsing features. You perhaps could disable safe browsing if you need to download a number of files that you know to be safe, and then you could re-enable safe browsing afterwards.
Using Edge Chromium ver. 88.0.705.68 when trying to download a filename.jlnp file from a server inside our organization we are prompted with the following message. Is there a way to stop this message from coming up and downloading the automatically?
I had this problem and downloaded Chrome browser which worked without a problem. Chrome did ask me whether I wished to download a potentially unsafe file which I had arranged in MS Access and downloaded previously without the problem I experienced using Edge. I completed the task in 5 minutes.
You can enable this policy to create a dictionary of file type extensions with a corresponding list of domains that will be exempted from file type extension-based download warnings. This lets enterprise administrators block file type extension-based download warnings for files that are associated with a listed domain.
Consider the following scenario. You turn on the SmartScreen Filter in Windows Internet Explorer 9 and then try to download a file type that is supported by SmartScreen Application Reputation. In this scenario, the following warning message unexpectedly appears on the download notification bar in Internet Explorer 9:
The SmartScreen Application Reputation service checks the reputation of a file. Therefore, you should not see the generic "This type of file could harm your computer" warning message when you try to download a file type is supported by SmartScreen Application Reputation. This issue occurs because the file name extension in the URL differs from the actual file name extension. (The actual file name extension is specified by the "content-disposition: attachment" HTML header.) Because of the different file name extensions, the warning message is displayed incorrectly.
Such Windows behavior is designed to protect your computer from running potentially dangerous executable files that have been downloaded from the Internet or received from other untrusted sources. This security warning appears on all versions of Windows (including Windows 10, 8.1, and 7).
In Windows, you can completely disable applying zone information to files downloaded from the Internet using the special GPO parameter Do not preserve zone information in file attachment (User Configuration -> Administrative Templates -> Windows Components -> Attachment Manager). (adsbygoogle = window.adsbygoogle []).push();
In some cases, it is advisable to completely disable the appearance of the security warnings for certain file types (extensions) through Group Policies. Although, of course, this is not very secure, because the user can accidentally run something malicious.
We suggest that you first download the PDF form to your computer or network drive, and then open it with Adobe Reader and fill it. You can either type information directly into each field, or copy and paste text. The font is preselected and cannot be changed. You can only type regular text (upper and lower cases); the system will not accept underlined text, bold or italics, script or formulas, curved or slanted apostrophes, double quotation marks or long dashes.
To open and complete the PDF application forms, you will need Adobe Reader (the latest version is recommended). If you do not have it installed on your computer, you may download the latest version free of charge from
Fillable PDF forms may be completed and saved using Adobe Acrobat Reader (this software must be loaded on your computer). To accomplish this you must first save the empty form on your own computer:

You might choose to purchase full-service antivirus software or take advantage of a free tool that operates automatically or manually. You can check your entire computer, multiple files at once, or separate files one at a time. Before you choose a method, consider which option makes the most sense for how many PDFs you need to check and how often.
If you are on a Mac operating system, the built-in antivirus technology called XProtect will automatically scan files and block downloads if it finds a threat. However, antivirus software companies argue that with the increased use of Apple technology, this built-in feature may not be able to keep up with advanced threats.
Google checks websites to see whether they host software or downloadable executables that negatively affect the user experience. Malware and unwanted software are either downloadable binaries or applications that run on a website and affect site visitors. You can see a list of any suspected files hosted on your site in the Security Issues report.
Malware is any software or mobile application specifically designed to harm a computer, a mobile device, the software it's running, or its users. Malware exhibits malicious behavior that can include installing software without user consent and installing harmful software such as viruses. Website owners sometimes don't realize that their downloadable files are considered malware, so these binaries might be hosted inadvertently.
Be sure that you don't violate the Unwanted Software Policy, and follow the guidelines given here. Though this list isn't comprehensive, these behaviors can cause apps and websites to display warnings to users upon downloading and visiting. You can see a list of any suspected files hosted on your site in the Security Issues report.

Sometimes people can end up inadvertently changing settings of frequently used applications without even knowing what they did wrong. One hasty click on a setting can prevent you from performing your regular tasks or cause a potential vulnerability that can harm your computer.
Google Chrome gives an option for downloaded files where you can choose to open certain file types automatically after they are downloaded. This can cause a malicious file from immediately being executed, possibly even before your antivirus is able to quarantine it. If you have accidentally messed up your Chrome settings and want to take back control of how you open Chrome files once they are downloaded, then here is a simple guide to help you out.
Step 3: Find the Downloads section and click Clear auto-opening settings. This will revert your browser back to default settings and allow you to only open Google Chrome files manually, after they are downloaded.
