I'm having a big problem with downloading the TeXLive distribution, as Windows considers it a virus, and I've tried more than 20 ways to deactivate Windows security, but it didn't work. So what is the solution?

I use Windows 10, I don't use any other security software, and I use an administrator account.

  • According to the comments, the OP has a Windows tool called "SmartScreen" installed, see here.
  • The OP had to remove the domain in question from the filter: "Finally, after 48 hours of work, I found it, I deleted SmartScreen Filter."

When you use the new Microsoft Edge, Microsoft Defender SmartScreen helps you identify reported phishing and malware websites and also helps you make informed decisions about downloads. [...] SmartScreen checks files that you download from the web against a list of reported malicious software sites and programs known to be unsafe. If it finds a match, SmartScreen will warn you that the download has been blocked for your safety. SmartScreen also checks the files that you download against a list of files that are well known and downloaded by many people who use Internet Explorer. If the file that you're downloading isn't on that list, SmartScreen will warn you.

I can only surmise what happened, but I think that you downloaded the file and got an Information window like ,,Your computer was protected by Windows Defender".

I suppose that this is caused by the file not being signed. (with a cryptographic certificate) This is a protection mechanism to prevent users downloading suspicious software.

Solution: When the information window appears, click on the ,,More Info" (or similar) button. A Button named ,,Execute anyway" (or similar) will appear. Click on it.

Please note that my PC's language is not English (and I am not a Native Speaker), therefore I cannot give you the exact button descriptions.

  • Unfortunately, you can't, after downloading the file, Windows tells you that "the file is malicious", then you press keep it anyway, but when you run the program - to decompress - it tells you that it is unsafe and gives you no choice but to exit.

  • It works for me. Did you execute the downloaded file as administrator? Commented Oct 16, 2021 at 23:23
  • Finally, after 48 hours of work, I found it, I deleted SmartScreen Filter. You probably don't have a SmartScreen Filter on your computer, and that's the difference. Am thankful.
