Press-Tab is a type of adware that affects computers and web browsers. It is a potentially unwanted program (PUP) that infiltrates the system and modifies the browser settings without the user’s consent. Once installed, Press-Tab starts displaying intrusive advertisements, such as pop-ups, banners, and in-text ads, to generate revenue for its developers. This adware is designed to redirect users to specific websites and promote certain products or services, often leading to potentially malicious or unsafe websites.
Press-Tab typically infects computers through various deceptive techniques. It can be bundled with free software or distributed through fake software updates or downloads. When users unknowingly download and install software from unreliable sources, the adware may be included as an additional component. It can also be spread through malicious websites or infected attachments in spam emails. Once installed, Press-Tab alters the browser settings, such as the homepage, default search engine, and new tab page, to redirect users to sponsored websites and display unwanted ads. This intrusive behavior not only disrupts the browsing experience but also poses a potential threat to the security and privacy of the affected computer.
