To remove third-party antivirus or similar security software in Windows:

  1. Open Start > Settings > Apps.
  2. Find the antivirus, antispyware, or other security app in the list.
  3. Select it, then choose Uninstall.
  4. Restart the PC if prompted. A restart is commonly required after each uninstall.

If the app does not uninstall completely, use the cleanup or uninstall tool from that software publisher’s website, or contact that publisher’s support.

Important cautions:

  • Do not run more than one real-time antivirus or antispyware product at the same time, because it can reduce performance, cause instability, or lead to update/install errors such as 0x80070643.
  • When removing security software, the PC can be left unprotected. Make sure Microsoft Defender Antivirus is enabled and Windows Firewall is turned on.
  • To check or change Microsoft Defender Antivirus: Start > Settings > Update & Security > Windows Security > Virus & threat protection > Manage settings > Real-time protection.
  • For better protection, turn on Cloud-delivered protection and Automatic sample submission.

If a security program is not listed in the normal uninstall list, check Control Panel > Programs > Programs and Features and uninstall it there. If it still is not listed, some programs include their own uninstall file inside C:\Program Files or C:\Program Files (x86). Use that uninstall file if present.

Do not manually delete the program folder if no uninstall file exists, because that can affect Windows or other programs.

Hi Gisele Girouard,

I understand you would like to remove any third-party antivirus or similar security software from your computer.

Could you let us know which version of Windows you are using and the names of the programs you want to remove? Some antivirus products install additional components, so removing only the main application may leave services or browser extensions behind.

At this point, I recommend that you review and try the steps provided in the AI generated answer on your thread. That reply typically include the most relevant checks for this scenario. 

For the cleanest removal, I recommend checking the antivirus provider’s official website for its dedicated removal tool. After running it, restart the computer and open Windows Security to confirm that Microsoft Defender Antivirus and the firewall are active.

Please avoid deleting security program folders manually, as this may leave drivers or services behind and cause problems later. If you share the program names, I can point you toward the appropriate official removal method. Thank you so much for your understanding.
