What is ProPDFConverter Toolbar? And how does it work?

ProPDFConverter Toolbar is a suspicious program developed by Mindspark Interactive Network (also known as IAC Applications). This program offers to convert PDF files to other file formats. Needless to say, it lures users by promising to provide quick PDF conversion process. Though it may seem like a useful application, security experts considered this program to be a potentially unwanted program (PUP) because of its questionable traits. Shortly after its installation, this PUP will alter the browser’s settings by setting itself as the new default search provider. What’s annoying is that if you don’t want to use it as your search provider, it will be hard for you to change the settings of your browser back to the way it was before.
This toolbar also has the habit of generating annoying ads and collect non-personally identifiable information from its users such as email address, IP address, browser type, browsing history, ads clicked, search queries and other information related to the browsing activities of its users. The information may be shared with its affiliated third-party companies and use it to provide more customized and personalized ads to its users. Obviously, it’s aiming to increase its profit from pay-per-click marketing by doing such things – things that wouldn’t bid well for your privacy. If you value your privacy much, keeping this toolbar installed in your computer won’t do your privacy any good.
How is ProPDFConverter Toolbar distributed?
ProPDFConverter is being distributed at the Chrome Web Store. However, it was also found to be traveling in software bundles as an extra component. Such trait is common for potentially unwanted programs which is one of the reasons why ProPDFConverter Toolbar is categorized as one. When you install a free software package with the ProPDFConverter Toolbar hidden in it using only the quick installation method, you end up installing this PUP as well. To make sure that won’t happen again, you have to opt for the Advanced or the Custom installation setup the next time you install free software packages to avoid getting hijacked by unwanted programs.
