Vuttiva Firewall is a free alternative to Windows Firewall or anyother application. It features IP search, huge performance, easy yet powerfull interface, port scanning, stealth modus, port closing, highly customisable.
When other programs or processes attempt to access your Internet connection attempting to use your Internet connection to communicate with the outside world, a window pops up that prompts you to permit or deny access on a per-application basis thus protecting you from incoming as well as outgoing traffic to ensure that only legitimate traffic is allowed, & alerts you to attempted intrusions & protects you from any local applications too preventing worms, Trojan horses & spyware programs from hurting your computer. If an unknown outside source attempts a connection to your computer, a pop-up window alerts you to the intrusion & again prompts you to choose whether to grant access. Vuttiva has an up-to-date list of known trojans to protect your computer against internet virusses and malware. But as this is a firewall, only network attacks can be monitored. You cannot use Vuttiva as your main antivirus solution.
