Pureweb Adware


Pureweb is an undesirable browser-redirecting app that will continuously display obstructive and unreliable ads in the main browser of your computer. Pureweb will also try to redirect your searches to sites that may not be safe for your PC’s security.


The Pureweb adware is programmed to swarm your browser with ads

Adware is one of the most common types of potentially unwanted software as well as one of the most irritating ones. If you are on this page, the chances are that you most probably had the “luck” to land one of its latest representatives, an app called Pureweb. Normally such applications get integrated in the users’ browser automatically (the browser could be Chrome, Firefox, Edge, Opera, IE or any other) and then begin to force it to generate hundreds of sponsored advertisements, from the moment you open a new browsing session. The result is that your screen typically gets filled with all won’t cease to show up no matter how hard you may try to close them. Oftentimes, this behavior could be mistaken for a virus infection and could set some of the users in panic. After all, the Internet is full of nasty threats like Ransomware, Trojans, Spyware and more, and nobody wants to have a close encounter with one these. Pureweb, however, is not a representative of any malware category. Therefore, you don’t need to get so stressed about it. This is just an aggressive online advertising tool which is programmed to swarm your browser with ads. In the next lines, we will tell you the most important things that you need to know about this application as well as the best methods to remove all of its ads and uninstall it all by yourself. For this, we have prepared a special removal guide you can find below that is packed with step-by-step instructions and an automatic removal tool for those of you, who don’t want to tinker with their computer settings and want to bring their favorite browser back to normal without losing time. So, if you have had enough of this particular application and want to get rid of it, stay with us.

Is Pureweb a dangerous application?

As we have already clarified above, Pureweb belongs to the category of software known as adware. But what does adware actually mean? Adware is a term that describes applications which specialize in generating a variety of advertising materials on the users’ browsers in order to promote certain goods and services to them. The manufacturers and the distributors of the goods and services which are getting promoted benefit by gaining more exposure and traffic to their sites. The adware developers also benefit from creating applications like Pureweb and Index for Captchas. They typically earn pay-per-click revenue from the ads, links and the offers that their software displays. The users, however, are the ones that have to constantly endure ads interruptions during their regular browsing and are forced to deal with hundreds of aggressive promotional messages. And this is where the major problem lies. Few people would like to see some unknown and uninvited application mess with their own browser. Moreover, the random ads and redirect links may not always be as safe as they seem. Misleading offers and fake messages may sometimes sneak inside the constant ads stream and if you are unlucky to click on them, you may land on shady web locations where threats like Ransomware, Spyware or other viruses may lurk. In this regard, we usually recommend you do not click on anything promoted by the adware and instead use the instructions above to uninstall it.
