Tuvaro is free browser add-on, which is advertised via other free software downloads. Once installed on a compromised PC, Tuvaro will add the Tuvaro Toolbar, change the default homepage and search engine of the hacked web browser to tuvaro.com. The Tuvaro Search Bar will display advertisements and sponsored links in victimized search results, and may gather search terms from search queries of an affected Internet user. Tuvaro Toolbar gets on the vulnerable computer after the PC user has installed another free software product or add-on that had bundled into their installer Tuvaro Toolbar. For example, when the computer user installs vPlay, he/she will also agree to change the default browser homepage and default search engine to tuvaro.com, and install the Tuvaro Toolbar. However, when the computer user uninstalls vPlay from the computer, the web browser's default settings will not be restored. This means that the PC user will have to remove Tuvaro Search from the favorite web browser manually.
