I'll write no.
The stock install of XP will become re-infected with MS Blaster, Nachi, Welchia or other moments after connecting to the internet. Installing an Antivirus doesn't stop these worms.
And for most, this is how you would get the update.
A far easier choice is to fix the issue and remove the virus/worm/trojan/pest/spyware/adaware/other or in a grander term PARASITES.
You can reinstall the OS, but for most, you just end up back at the beginning, but with more headaches as you chase down drivers for motherboard, USB, video, cameras, printers, and what else?
