Lightening-search.com is a basic search engine that does not receive a lot of attention. This is probably the reason why its administrators have decided to resort to using Potentially Unwanted Programs (PUPs) and browser hijackers to bring more users to their website – the aforementioned software types may often be installed stealthily, and they will command your Web browser to use Lightening-search.com as your search engine or default new tab page This change is intrusive but not harmful – it should not be considered as a major problem. However, it goes without saying that most users are unlikely to enjoy the change, and they will be interested in learning how to revert it as soon as possible.

The good news is that dealing with software that manipulates your browser's settings is a straightforward and easy task – all you need to do is run a suitable PC security utility that will detect and remove the intrusive software. Its removal should be enough to get your browser settings back to normal.
