Updating zone files
We all have had problems with machines being overrun by malware: taking 20 minutes to startup, constant popups, hijacking of the home and search pages, bookmarks being added, etc.
(There is an irony here, as some of the more “evil” malware hijacks your host file to prevent their removal or to redirect search queries).Unfortunately, there are several problems with using host files, especially in a corporate environment: As an alternative to host files, there are several desktop-based DNS software packages available which are designed for use on a single desktop.These packages were originally designed as a substitute for a large host file in order to speed up browsing by having a local name server available to cache domain queries such as DNSKong.No product is 100% effective against viruses or spyware.Zone Alarm’s advanced firewall monitors behaviors within your computer to spot and stop even the most sophisticated new attacks that bypass traditional antivirus and security suites.One of the more popular techniques for fighting malware among home users is through the use of a host file for DNS redirection.
A host can be used to maps hostnames associated with malware to a different IP address (such as a loopback address, 127.0.0.1).
The domains are loaded onto an internal DNS server.
When a computer requests a URL or file from one of these domains, a fake reply is sent, thus preventing many malware installs from occurring.
Opens email attachments and web downloads in a virtual cloud environment to see if they are safe.
Protects your computer from web threats before they reach your browser.
Monitors programs for suspicious behavior spotting and stopping new attacks that bypass traditional anti-virus protection.
