Thank you for the advice.
I installed Online Armor successfully. Rebooted and the system loads into Windows, but the screen freezes on the desktop and Avast has the yellow warning sign on the icon near the clock.
Booted into safe mode, uninstalled Online Armor and the computer is booting correctly.
Online Armor does not like the laptop (or Avast!).
Should I try Comodo? I really think the Laptop is too old to handle a 3rd party firewall and Avast.
It is an ASUS laptop Intel Pentium M Processor 1.6GHz with 1.0Gb Ram and a hard drive of 76Gb. Windows XP SP3 fully updated is loaded on the system!
Best regards,
