After updating to latest version of Firefox i am unable to access internet. Get message Unable to find proxy server. This update also disable internet explorer so I cannot use it to access either. The desktop that I am having trouble with is running Windows XP Professional.

hi, please check in the firefox menu ≡ > options > advanced > network > connection - settings... if firefox is set up to directly connect to the internet ('no proxy').

and maybe also run a full scan of your system with the security software already in place and different tools like the free version of malwarebytes, adwcleaner & kaspersky security scan.
