Computer users that love to play quick and fun online games may stumble upon the Playlunar.com site and be attracted to titles like ZigZag Twist and Combo Crusader. The premium games at Playlunar.com are available only to those who install the Play Lunar browser-based gaming platform and are willing to support the Play Lunar platform by watching video commercials and other ads. Security authorities report that the Play Lunar platform is supported by advertisements and may appear in your browser as an extension, add-on, and Browser Helper Object named PlayLunar. The PlayLunar program may be your ticket to the VIP zone of the Playlunar.com site, but you should keep in mind that you need to watch a few commercials before you start pillaging islands in the world of Pirate Hunter. Many users may not be comfortable with the ads by PlayLunar and wish to use an ad-blocker to continue playing premium games at Pllaylunar.com and skip the ads.

However, that is not possible because the PlayLunar platform has a blacklist of extensions and it may try to uninstall applications like AdBlock Plus by Eyeo GmbH and similar tools. The play Lunar gaming extension is considered to be a Potentially Unwanted Program (PUP), and you need to take into consideration its cons and pros carefully. The PlayLunar platform may make unwanted changes to your Internet settings and redirect you to suspicious pages that may host disturbing content. You should know that the PlayLunar extension is not secure and may download corrupted data on your PC. Also, the PlayLunar extension does not use SSL encryption, and you may be exposed to cyber threats like JS/Agent.NKW and HTML/iFrame.B. The PlayLunar extension is similar to the FunPopularGames Toolbar and GreenGame, and you should use a credible anti-spyware instrument to remove its files completely.
