I am currently trying to uninstall Avast, however I simply can't because I forgot the security password (not the ACCOUNT password)

I’ve tried everything I can, but I’m unable to change it. This is my last resort, so any help would be much appreciated.

Its hard to suggest something, if as you say you have tried absolutely everything, can you be a little more specific.

Have you tried this:
Clean Reinstall - 1. - Download the avast! Uninstall Utility, avastclear.exe Avast Removal Tool | Download Avast Clear | Avast and save it to your HDD. Make a note of the steps required or print the page.
2. - Download the latest Avast off-line installation file for your Avast Program.
3. - Follow the instructions in the link in 1 above.

This does not work without the security password

It does, as the clean uninstall needs to be run from safe mode where Avast won’t be running.

Clean Reinstall
As per the instructions in the link given previously.

Here’s how to uninstall Avast on Windows 10 using Avast Clear:

  1. Download the avastclear.exe uninstall utility and save it to a familiar folder on your PC (saved to Downloads folder by default).
  2. Right-click the file and select Run as administrator. If prompted for permissions, click Yes.
  3. Click Yes in the Avast Clear dialog to start your PC in Safe Mode.
  4. Select the folder containing your Avast program files, and select the Avast Antivirus product you want to uninstall (the location and product are usually detected automatically). Click Uninstall.
