This website is for a company that purports to offer technical support for reputable companies, such as Microsoft, Frontier Communications, Google, etc. They do so by purchasing keywords for the words "technical support", combined with the target company's name. However, they are actually criminals that falsely represent themselves as authorized technical support staff, directing the end user to install malicious software and visit malicious web sites, after which they claim to have found "hackers" on the end user's system. They then offer to provide protection against these manufactured threats by giving the, by now frantic, end user security software and services for a measly $700 for life, or $200 per year. Steer clear of this company and report them to law enforcement at every opportunity.
