The word “Patch” in software development means an update for newly discovered critical malfunction or vulnerabilities. Such Patch has to be developed and deployed quickly, before someone can take advantage of using these vulnerabilities. K-Lab saying in release notes that Patch (C) has fixes to some vulnerabilities, so we, who use KIS, are actually using a software has vulnerabilities that can be exploited by anyone, like hackers. Any get the Patch so far? If Not, what K-Lab waiting for? To be hacked through a software designed to protect us from hacks? This is very weird!!!
