These annoying adware invades the system and immediately starts to make changes that you never wished to have. It starts with highly irritating ads in your browser and can extend to more devastating results such as spyware and such programs automatically installing in your computer and may finally have to face the consequences such as the Blue Screen of Death.

But what this adware mostly does is bombard you with an unlimited number of ads and banners. It does not care whichever time you are browsing the internet; it just throws a popup banner or fake promising ads. And it does not bother what type of ad, it just fills the advertisement on your screen. This can go as far as your browser window being entirely covered by ads and banners.
