About this contamination
Pop-ups and reroutes like Rompilsy.com are commonly occurring because of an advertising-supported software set up. If enough attention was not paid when you were installing a freeware, this is how you could have ended up with ad-supported program. Not everyone will be aware of the signs of a contamination therefore, not all users will understand that it is indeed an ad-supported program on their OSs. Since adverts are how the adware makes income, expect the adware to expose you to as many adverts as possible but do not worry about it directly jeopardizing your operating system. It might, however, lead you to a malicious page, which could authorize malware to enter your device. If you wish to keep from endangering your system, you will have to eliminate Rompilsy.com.
