What is Best File Converter? And how does it work?

Best File Converter is a browser extension that allegedly allows users to convert various file formats into a PDF format. Its interface contains quick links to popular sites. As useful as this browser toolbar may look, it’s not really what it seems to be as security experts found out that it’s actually a browser hijacker that could hijack your browser’s settings the instant it gets installed. In fact, it is created by Polarity Technologies Ltd. – a company notorious for developing browser hijackers and unwanted programs.

If installed, it will quickly change the default new tab page, homepage and the search provider to its own settings without your consent. This kind of behavior is common for browser hijackers. As a result, whenever you browse the internet, you will experience sudden redirects to suspicious websites. Apart from redirects, you will also see tons of ads from banners, in-text links to pop-ups and many others. Some of them could even reroute you to unknown and questionable websites that may contain malicious programs or content that could harm your computer. It was also determined that like other browser hijackers, the Best File Converter is also capable of tracking down your browsing activities so it can collect data. It may include your IP address, search queries, websites you’ve visited, ads clicked and other browsing-related information. The collected data may be used and shared with third parties in order to deliver you with more ads. Needless to say, instead of improving your browsing, Best File Converter only ruins it.

How is Best File Converter distributed online?

Questionable programs like Best File Converter can be found in free sharing sites as a part of software bundles where along with other unknown programs, it is added in the optional components. This is why installing software bundles is quite tricky since you could end up installing not just one but lots of programs in a single installation. To prevent this from happening, you need to use the Advanced or Custom setup instead of the standard one as it lets you get rid of any additional programs that may have been added in the package before you proceed with the installation.
