How to uninstall PlatformDeploy from Chrome, Firefox, Safari

What is PlatformDeploy?

The security researchers have determined that PlatformDeploy is a potentially unwanted application (PUA) that belongs to the category of browser hijackers. The aim of browser hijackers is to generate advertising revenue. For example, a browser hijacker redirects the user’s homepage to the browser hijacker’s page that contains ads or sponsored links; a browser hijacker redirects the user web searches to a link the browser hijacker wants the user to see, rather than to legitimate search engine results. When the user clicks on ads in the search results, browser hijackers makers gets paid. The developers of browser hijackers can collect privacy information such as user browsing habits as well as browsing history and sell this information to third parties for marketing purposes.

Most often, browser hijackers promote fake search engines by setting their address as the default search engine. In this case, the PlatformDeploy hijacker installs search.rktz9.com as a search engine. This means that users whose web-browser is affected with the browser hijacker are forced to visit search.rktz9.com each time they search in the Internet, open a new window or tab. And since search.rktz9.com is not a real search provider and does not have the ability to find the information users need, this webpage redirects the user’s browser to the Yahoo search engine.

In addition to the above, PlatformDeploy can be used to collect your privacy info which can be later transferred to third parties. You do not know if your home address, account names and passwords are safe. And of course you completely don’t know what will happen when you click on any ads on the PlatformDeploy web-page.
