If you’re wondering why your entire screen is covered with ads, banners, and different popping messages, you should know that an adware application known as Winsap.dll stands behind this activity. This is specific software, developed to generate advertising messages of all types and in case you have recently been disturbed by its aggressive behavior, here you will find a solution. Below is a removal guide which will help you permanently remove the source of your annoyance by manually deleting the adware related files. Before you do that, however, we suggest you take a look at the brief explanation in the next lines. It will give you an idea about the specifics of the ads-generating software as well as some tips on how not to get infected with it in the future.

Being bombarded with ads all over the screen – why is all that for?

As typical adware, Winsap.dll is a piece of software that has been developed with the idea to display huge amounts of ads all over the monitor. Banners, popping boxes, blinking messages, short notifications, full-screen ads and new browser tabs appear the very moment users open their browser. They pop-up in the sidebar, the headline, the front page, and may even take the entire screen when it seems impossible to skip them or get them closed. Why is all that for? The clicks! It is all about the clicks! The main reason that adware ads are so intrusive and aggressive is because they want you to click on them. And these clicks don’t go in vain. A remuneration scheme called Pay-Per-Click converts them into a nice income for the adware developers. This explains why they have programmed it to behave so intrusively.

You have probably noticed that the issue with the annoying ads appeared when Winsap.dll started to operate on your PC. However, you may not really remember installing this particular program. But there is a chance you installed some other software recently and this is probably how you ended up with the adware as well. How did this happen? A software bundle is the most common way. Usually, software developers tend to include adware-like applications inside the installation packages of some other software. This practice, although it may appear a bit shady, in fact, is a perfectly legal one and it helps many programmers “sponsor” their software and release it for free by earning just from the adware. One way to avoid the additionally bundled applications to get installed on your system is to pay close attention during the installation setup process. While the standard/quick option would install the whole package as it is (including the adware), the advanced/custom one would give you the option to manually choose what you want to install and what not. We would advise you to always go for the second option as it would prevent unwanted programs from getting installed unnoticed.

There are some potentially undesired activities that users may experience while an adware like Winsap.dll operates in their system.

Adware may collect various data, related to your browsing, your latest website visits, online purchases, searches, social profile activities, online locations and so on. This data, known also as traffic data, is usually collected with the idea to be analyzed by the adware developers, who can then display more ads, relevant to your interests. This way they believe the chance you click on some of them may improve and so will the income the programmers can generate from these clicks. Unfortunately, it may not be really clear how safe this data is transmitted and kept and what happens to it in case it gets sold to third parties. The EULA may provide more details about the collecting policy and storage, but there are users who would just directly uninstall Winsap.dll rather than be concerned where their traffic data goes.

Another thing that may bring you some irritation is the change in the browser’s behavior – the homepage may be replaced by a promotional landing page or an unknown website, your search engine may be changed and a new tab with dozens of eye-popping ads may greet you from the screen. Users who are facing this for the first time would naturally think that they have been infected with some virus. However, an antivirus scan will not detect adware like Winsap.dll because it does not contain malicious scripts. Actually, this type of program is generally harmless and cannot perform direct malicious actions on your system. Adware is nowhere near the harmful capabilities of viruses, Trojans, Ransomware, spyware and other malicious threats, which include self-replicating, stealing valuable information, encrypting your data, blackmailing you and many more criminal deeds. However, the unpleasant browsing disturbance and the constant irritation caused by the ads is usually enough for the users to decide to uninstall the adware. For those of you who wish to do so, we have prepared the removal steps below. Just make sure you follow them closely and you will be able to save yourself from Winsap.dll completely.
