Every time I open a website, there are annoying popups that would show up. Sometimes it would also ask me to allow or trust a certificate, which I am unsure of. I would really want to get rid of them because I am quite concerned that it may be a virus or something. I just wanted any advice whether I can do something about it on my own or do I have to go to the apple store to get further help.
Please help!
MacBook Air, OS X Yosemite (10.10.2)
Click here and follow the instructions, or if there’s a type of adware not covered by them on the computer, these ones. If you're willing to use a tool to remove it(you don't need to, but may find it easier), you can instead run Adware Medic; this link is a direct download.

I clicked on the X button to close it and usually I get redirected to this site http://luu.lightquartrate.com/

You should never permit the installation of something you are unsure of.
You may have inadvertently installed adware. You do not need to download or install anything to fix it.
For a description of how this may have occurred, how to avoid it in the future, and for Apple's recommended actions read How to install adware. Apple's instructions are linked in the Recovery Procedure near the end of that document. Read and follow them carefully. Pay particular attention to the easily overlooked passages directing you to restart your Mac when required.
Open Settings; click on Safari; Click on Clear History and Website Data and the pop ups are gone!
