It seems that I have accidentally downloaded an adware program called Capricornus. When I browse the web, I always receive many ads by Capricornus. I close them again and again, but they keeps popping up. I find an article when searching in Google and its authors also say that Capricornus is adware. I have tried following the guide given in that article, but somehow it did not work. I have also follow other guides in other articles, but none of them help me. Could anyone help me?
