Desktop Armor watches your computer for changes, immediately notifying you when a setting is altered to confirm you want to keep or reject the change. This catches many of the modifications made by a virus, trojan or worm; protecting your computer from harm. (A "Computer Setting Firewall" is an excellent description.) It includes other features to help you protect your computer from hackers and worms by disabling rarely used Windows services, it helps you protect your privacy by blocking popup advertising windows, blocking "Phishing" scams, and removing "Web Bugs" used to track you. Desktop Armor has more tools to fix you computer if Internet Explorer has been hijacked, to easily look at all the programs that will start when Windows starts, to let you see where the space is being used on your hard drives, and more!
