Some info about it
PC Health Kit can infect a computer a variety of ways. PC Health Kit can be manually and voluntarily downloaded and installed via Safecart and third-party installations including freeware, shareware, codecs, and torrents, as well as browser add-ons, extensions, and toolbars. PC Health Kit may even be promoted on such as websites as download.com and eazel.
Though PC Health Kit can be voluntarily downloaded, PC Health Kit primarily infects computer systems without consent, often bundled with malware, software, and files previously mentioned such as fake Flash players and especially Internet Helper Toolbar and LessTabs adware. In fact, Internet Helper Toolbar may display results and notifications from PC Health Kit in the middle of the unethical toolbar’s interface pictured below as a blank area before the Amazon button.
