The anti-hacking is used to describe the level of protection available on your computer. From firewall to antivirus solutions, Internet settings, etc. That's the general level of informing you how well the computer where the tools are installed is defended. Of course, this notion should be considered simply as another piece of information. There are trojans, rootkits that have the possibility to bypass all the security measures. In the end, it's all limited to your browsing behavior (application installation included).
