Online Armor is a security system that protects your computer against spyware, malware, Trojans and phishing attacks.The first time you initiate the program, you have to set up its configuration. You can enable Online Armor to automatically trust everything found by the wizard on your computer (so, you do not have to confirm any action).Otherwise, it can guide you through a step-by-step wizard at the end of which you can set your own preferences. The last option should be mainly used by power users.In the Safety Check wizard, Online Armor goes through the latest product updates, searches for known dangerous processes, explores the Start menu and system files, and checks autoruns. Once you have gone through the remaining steps, you have to restart the computer, so Online Armor can finish its learning process.The user interface of the program is simple and straightforward. On the right side you can select Status, Firewall, Domains, Programs, Autoruns, Anti-Keylogger, Hosts file, History and Options.You can allow or block access to various programs in the firewall settings, as well as edit ports, view a list of available networks, add domains and set their status (trusted, blocked, protected), but also control program behavior (e.g. make them run safer than normal).Plus, you can check autoruns (allow or block them), view a list of available keyloggers and decide whether you trust them or not, monitor changes made to the Hosts file, view a history list of alerts and actions you took in Online Armor, and configure options, of course. In Options, you can enable debug mode, change interface language and update auto-check, enable logging and configure its default level, add items to the exclusions list, and others. Unfortunately, the option to backup and restore files, as well as assign hotkeys to various commands is not available in the free version of Online Armor.The bottom line is that Online Armor offers a great level of protection for your computer, but you can purchase the premium version if you want additional security. Until then, enjoy this free version.
