Ads by LightsOff. How to remove? (Uninstall guide)
What is LightsOff?
Developed by Coffee and Comfort Apps LLC, LightsOff is yet another application, which aroused various discussions on the Internet. Some people (probably promoters and affiliates of this app) claim that it’s a very handy application that perfectly works on Google Chrome, Mozilla Firefox, And Internet Explorer. They claim that it enhances the quality of online videos, “set the mood and dim the lights” when needed. However, security experts have a ‘slightly’ different point of view towards this program. They claim that it’s yet another adware and a potentially unwanted program (PUP), which may not only initiate unwanted activities on your machine, but may even infiltrate your computer without asking for an appropriate permission. As soon as LightsOff virus is installed, it may activate cookies or tracking software on your web browser and start accumulating search terms, most frequently visited websites, data entered in them, clicks, IP address, email address, PC’s location and so on. Such data is usually used for advertising purposes; however, who knows where else third parties may apply it. By the way, once this adware hijacks web browsers, it may start initiating commercial advertisements on every websites that you visit. Usually, LightsOff ads inform about various deals, discounts, lowest prices, coupons and so on. However, we highly recommend you to stay away from each of them since in reality they may be filled with links to unknown, suspicious or even unsafe third party websites. Therefore, if you have already started experiencing LightsOff redirects to unfamiliar websites and other inconveniences that might indicate that this adware hides in your machine, we highly recommend you to check you machine with Reimage (Windows OS) or Webroot SecureAnywhere AntiVirus (Mac OS X). You can do that manually as well (the guide is given at the end of this article); however, we highly recommend you to remove LightsOff virus automatically in order to get rid related registries and other PUPs that might also entered your machine via freeware.
How can LightsOff hijack my computer?
LightsOff is promoted via its official website; however, it can seldom be found spreading on its own. Users are usually introduced with it during the installation of another freeware. That’s because it’s developers (Developed by Coffee and Comfort Apps LLC) rely on a misleading distribution method, which allows distributing this app as a ‘recommended’ application along with other freewares. Be aware that it may be added to any kind of free program despite it’s reliability, functions, and other things. Therefore, to prevent installing LightsOff adware, you should select Advanced or Custom installation option whenever you decide to install a freeware and carefully follow the entire installation wizard. In order to keep your computer PUP-free, it’s a must to detect all ‘additional components’ that may spread along with the freeware and opt out of them.
If you have installed LightsOff virus manually from it’s official website, most probably your web browser’s homepage and search engine have also been modified since this adware is promoted along with a suspicious search toolbar on the official website.
