Hi Nalinee, last time I checked it was enough to uninstall Meteoroids adware using Control Panel to eliminate the unwanted ads in Internet browsers. In some cases this adware was "supported" by other potentially unwanted programs so you should check your Control Panel and uninstall all suspicious programs. After double checking your Control Panel scan your computer with Malwarebytes Antimalware and Spyhunter, bother of these programs are capable of detecting and removing Meteoroids adware (and other PUPs created by "Small Island Development").
