I will definitely discuss Windows Defender
If you want disable Windows Defender permanently, you need to install another antivirus software: Windows will automatically disable the protection provided by Defender and keep active only that of the alternative antivirus installed on the PC (as keeping two antiviruses active on the system is harmful and slows down the general performance of the computer). If you don't know which alternative antivirus to install, take a "spin" on my tutorial dedicated to the best free antivirus for Windows 10.
How do you say? Would you like to disable Defender without installing other antivirus? This is a strongly discouraged procedure (you would expose the system to various types of cyber threats) and in fact Microsoft blocked this possibility starting from August 2020, with the release of Windows Defender 4.18.2007.8. It is possible, however, to put into practice a couple of "tricks" that (at least at the time of writing), seem to work.

But first you have to disable the Tamper protection Windows 10 from the menu Virus and threat protection> Manage settings di Windows security.

If you have second thoughts, to activate Windows Defender again, open the Registry Editor and delete the key DisableAntiSpyware you created earlier, by right clicking on it and selecting the item Delete from the menu that appears. The changes will take effect only after rebooting the system and clicking the button Restart in the Defender management panel.
Disable Windows Defender for only some files
If you don't want to completely disable Windows Defender, but want the software not to scan some specific files, you can take advantage of the system's exception system.
Therefore, access the Defender settings as I explained to you before, go to Virus & threat protection> Virus & threat protection settings> Manage settings and click on the entry Add or remove exclusions which is at the bottom of the page that opens.
Finally, press the button [+] Add an exclusion and choose whether to add a fillet, a folder, an file type specific or a process. In the first two cases, use the File Explorer navigation panel to select the file or folder to add to the exceptions. In the case of the "file type", instead, type the extension to add to the exceptions and click on the button Add. In the case of processes, type the name of the process to exclude from the scan and press the button Add.
If you have second thoughts, to remove an item from the exceptions, go back to the menu Virus & threat protection> Virus & threat protection settings of Defender, click on the name of the exception you added earlier and click on the button Remove which appears below. Confirm by replying Yes to the warning that appears on the screen.
