What is Code erreur b4259f ?

This program is designed to be able to integrate itself with all the browsers in your computer, be it Chrome, Firefox or Internet Explorer. Once it has wormed its way into your browsers, it will start to collect data and information about your browsing patterns and history, possibly also search queries and site visits. All these information that it has gathered will go towards helping it to generate suitable and believable ads to display to you. These ads are catered specially for you according to your taste and preferences (as analyzed by the algorithm). They may be in the form of banners, pop-up ads or boxes or even as a separate window. They may feature anything from deals to coupons to even, proclaiming that you are the recipient of a sudden windfall. Regardless of the messages that it touts or the form in which it takes, always bear in mind to not click on the ads.
Why should you not click on the ads?
The aim of the creators is to get you to click on the ads. Therefore, once you have done that, they would have succeeded.
Upon clicking on the ads, you will be directed to another webpage. The webpage that you are being directed to can vary vastly in terms of what it is and how detrimental the page is for you, as an unsuspecting user.
The page that you are being directed to may be lifted directly from your browsing history. Such pages, then, will not be of any use to you as you would have had known about the deals prior to clicking on the ads. It’s just a way to milk you for money as your click will make a tiny amount of profit for someone. There are also times when the page that you are being directed to is a one of the many third-party’s pay-per-click sites that are rampant on the Internet. When you enter such pages, a certain amount of money will be credited to the creator’s account. These sites are typically chained, so you may have to click multiple times on multiple sites in order to get somewhere useful. If you even click on an Ad and it doesn’t take you to the promised site just shut down the whole page. Chances are you won’t get anything useful anyway.
Sometimes, you might even be directed to a page that doubles up as a portal for other adware to access and invade your computer. If you do happen to be directed to such sites, you will notice an increased number of ads appearing.
Occasionally, you might also be directed to a page that aggressively prompts and promotes the download of a certain software. In such cases then, regardless of how “great” the software might seem to be, do not download said software. The software will typically be of lower quality than established software and/or cost more. The only way such software typically sells is through aggressive advertising – exactly what you are currently a victim of.
