How to Open Trusted PDFs from HP Smart Scan Safely

Select Language:

If you see a message on your computer that says “The file you are attempting to preview could harm your computer,” it can be scary, but don’t worry — most of the time, there’s no serious problem. This warning usually appears because Windows is being cautious about files downloaded from the internet or files saved from external sources.

Here’s what you should know and how to handle this situation. When you scan a document and save it to your local folders on your computer, opening it later may trigger Windows to show this warning. The alert is basically saying, “Are you sure this file is safe?” because the file came from an external or less trusted source. If you trust where the file came from, you can safely choose to open it.

Usually, this message is just a security feature to protect your device from potentially harmful files. If you do decide to open the file, you can click “Yes” or “Open” to view the contents. Just ensure that you trust the source of the file before doing so.

Now, about the structure of PDF files: PDFs are organized files made up of different objects like text, images, and graphics. They start with a header that includes specific identifying information called a magic number, followed by various objects arranged in a way that ensures the PDF will display correctly on different devices and platforms.

Sometimes, this warning might be triggered by the software you’re using to open the file, especially if it has built-in security checks. In some cases, examining the file’s metadata can give more clues about its origin, but you might need special tools to look inside the file structure deeply.

In summary, when you see that warning, trust your instincts. If you’re sure the file is safe, go ahead and open it. If not, it’s best to delete it or scan it with antivirus software. Always make sure to download files from trusted sources to keep your computer safe.
