Windows 10: Downloads error "the signature of this program is corrupt or invalid"

Hi, everything was working fine until today. Now, every download I attempt on Microsoft Edge comes up with the message "the signature of this program is corrupt or invalid".
I haven't made any changes to my PC, or installed any new software, and I cannot find any solutions to this.
Does anyone know how to cure this, please?
Many thanks. *Smile

Error - Signature of the program is corrupt or invalid.

Hi,

Thank you for posting in Microsoft in Community.

- Did you make any changes to the pc prior to this issue?
- Do you have the latest version of this software installed on the pc?
- Have you installed all pending updates on the pc?
- Is the issue specific to this program or software?


Lets perform a Clean boot and check if the issue persist.

When you start Microsoft Windows, typically there are several programs that start automatically and run in the background that may interfere with the program. These programs may include antivirus and system utility programs. When
you perform a clean startup procedure, you prevent these programs from starting automatically.

How to troubleshoot a problem by performing a clean boot in Windows:

Note: After you have finished troubleshooting, follow the steps under “How to reset the computer to start as usual after troubleshooting with clean boot”
in the article to boot to normal startup.

Also suggest you install any pending updates on the pc to check if that helps.

Updates are additions to software that can help prevent or fix problems, improve how your computer works, or enhance your computing experience.

Let us know if this helps.

Keep us posted for further assistance, we will be glad to help.

 

Error - Signature of the program is corrupt or invalid.

Original title : signature invalid or corrupt.

I tried to Neat Scanner Software and it says that the signature of the program is corrupt or invalid, any help would be greatly appreciated

 

Use another browser such as the built-in IE11 or install a 3rd party browser such as Chrome and see if you have the same issue.

 

Chrome works fine. Internet Explorer is fine. It just seems to be a problem with Edge.

 

I am biased, I openly admit.
I hate Edge and I will never use Edge.
I have been using IE since the Vista days and I am not going to change browser.

That's all I will say before I am accused of inflaming a "lightning fast and wonderful Edge ".

I apologize I am unable to help you fixing problems in Edge.

 

No worries, not too keen on it myself.

 

It's no fix, but I did find the following: (Dated 1.19.16)

Ref HERE.

I know there was no mention of that particular software, but I'm only using it as an example of one possible cause.
