WebShield by Irrational Number Applications or other publishers (also known as WebShield virus or Web Shield) is intrusive adware that serves deceptive pop-up advertisements across multiple internet browsers, including Google Chrome, Mozilla Firefox, Microsoft Internet Explorer, and Apple Safari. Advertisements displayed by potential WebShield malware will usually say something close to “Ads by WebShield” on them.
WebShield adware is promoted as a web tool and application that can help users “discover surprising trends and data” about the websites they visit. The program claims to alert users when they are being tracked.
WebShield serves ‘targeted’ advertisements to users while they browse the internet. This is a privacy concern because targeted advertisements can only be produced by the adware if it has access to user browsing data, such as all browsing activities, bookmarks, app data, and browser history. This information is observed and used to generate advertisements it feels users are most likely to click on.
Furthermore, WebShield bundles with additional unwanted programs, malware, and other possible malicious threats. This means that it might be necessary to uninstall multiple programs from Windows and remove multiple browser add-ons and extensions from Chrome, Firefox, Internet Explorer, and Safari. Many of these programs can not easily be found on a computer system without third-party security software.
Third-party programs and malware that can bundle with WebShield adware will cause other issues aside from pop-up advertisements. Other issues include unwanted browser redirections to sponsored webpages, like Jogostempo.com, corrupted computer productivity, and decreased internet speed.
WebShield adware and the additional programs that it bundles with also manufacture new tasks and change existing Windows start-up settings in order to run every time the operating system starts and remain enabled if disabled by the user. Programs and browser attachments that may arrive with this deceptive piece of adware can also cause other issues for computer and internet users aside from pop-up advertisements, including browser redirections and a loss in computer functionality and internet connectivity. Furthermore, if WebShield is manually removed, it is possibly that the adware or another one in its place will return before a week has passed.
WebShield adware is usually contracted without consent or knowledge of the computer user alongside third-party programs and files, such as freeware, shareware, torrent files, and other free downloadable content. The potentially unwanted programs (PUPs) and files that deliver the adware can be introduced to a computer system and affected internet browsers with or without user authorization.
Computer and internet users who seek to download and install free programs and files online may be presented with an opportunity to accept or decline a ‘custom’ offer to install WebShield adware and other programs during the setup and installation process. However, the request to decline WebShield adware from installing is often presented in a very confusing manner. In some cases, the download manager may completely ignore the user request to decline WebShield from installing and the adware will install against user consent and knowledge.
