    PhishBlock

    PhishBlock

    A program that detects and blocks phishing, pharming, Hacker's C&C.

    PhishBlock is a security program that detects and blocks Phishing, Pharming, Hacker’s C&C(Command and Control) Servers which are located in databases with URLs, DNS hostnames, and IP Addresses. This program detects and blocks Malware URLs, bad Hosts, and bad IP addresses. Recently, most malware codes are delivered covertly to users’ personal computers through Google ads, SNS, Blogs, BBS and so on, which users visit often. And After the malware codes connect the C&C server(or Botnet), they attack, and steal information, repeatedly and persistently. Currently, there is a lack of affordable software to protect individuals personal computer’s from detecting and blocking these malware features. Generally, virus vaccine programs only detect and block files already existing inside a users’ personal computer. But PhishBlock detects and blocks harmful files at the network entrance of personal computers.
