Yealt is an adware threat, which may be marketed via numerous downloads of free applications and, after installation, it may alter the Web browser's default homepage, search service or a new tab window with a sponsored website that is designed to possibly increase Internet traffic and generate advertising revenue from advertisement clicks. Yealt may create and show unwanted pop-up ads, deals, offers, sales and sponsored links in search results of any major search provider and may gather search terms from the PC user's search requests. Yealt may be distributed as an extra tool via unsafe downloads of other software, especially free applications that might have packaged into their installation wizard Yealt. When the computer user uninstalls Yealt from the computer system, the Web browser's default settings may not be reverted. This means that the PC user needs to remove Yealt from the PC with a genuine anti-malware program.
