AVG for Windows XP

I have rebuilt my daughter's old laptop with Windows XP after a crash, and now I cannot find a version of AVG to install. I have tried 5 different downloads, all of which tell me that the OS is not supported.

Looking on the AVG website for older versions yields only a series of pages that tell me to upgrade my version of Windows - something that I cannot do with this device.

Can anyone PLEASE help?  I am rapidly losing my composure.
