Windows 10: Why is it saying "antivirus scan failed" when I try to download ANY file?

Hey so I play the sims 4 and I have been trying to download a mod for the game and that requires me to download a file- when I did next to the file trying to download it says, "antivirus scan failed". I have tried downloading a third-party virus scanner and when I tried doing that, it said the same thing. I have gone into my regedit settings to try to fix this and restart my chrome. Nothing has worked and it is becoming frustrating, please help me.

:)

 

Antivirus scan failed

I cannot download any files as getting a message to say antivirus scan failed. I cannot turn defender on either and updates says error -" • Update for Microsoft Security Essentials - 4.10.209.0 (KB3205972) - Error 0x80070643"

Files all downloaded but last part of setup failed

There must be a way to temporarily disable Bitdefender, almost all antivirus have this option, take a deeper look into the user help.

 

Files all downloaded but last part of setup failed


Hi. I was invited to download/install Windows 10 and I followed all the steps to download the files. Then I clicked to install it and it seemed to be doing it. Windows closed down and the computer restarted, but when it opened again it was still Windows 7 and there was a box up relating to Windows upgrades that that said the 'latest upgrade' had failed, and there was a button to click to download Windows 10 if I wanted to (again?!). I don't know where all the files are that were downloaded and what I should do. I saw a suggestion somewhere that firewall/antivirus software can be a problem. I have Bitdefender, that doesn't allow you to disable it.. I suppose I could remove it completely before trying again? But otherwise what should I do? I don't want to download a lot of duplicate files again.

Thanks for any suggestions.
