my windowsxp is crashed after boot scan

i installed the last version of avast and had the boot scan,
after that, my windows XP restarts automatically after the loading screen.
i can’t find any recovery methods…

i am so sad after using the boot scan…Please help me to sort out the problem! :cry:

In XP, if you press F8 when starting Windows and select ‘Last known good configuration’ from the boot menu, the boot scan should not be started.

Can you test?
