How did I get infected with?

Fast Browser relies on malvertising. It pretends to be a great app and lures you into downloading it. The hijacker, of course, also has other tricks up its sleeve. It also travels the web hidden in bundles, fake updates, pirated software, and spam messages. There are myriads of malware distribution tricks. If you, however, choose caution over carelessness, you can prevent infections. The thing about this parasite is that it needs you (the user) to approve its access. No permission, no admission! The hijacker is bound to seek your consent. And it does. The hijacker always asks. But it does so in the sneakiest way possible. This menace hides in the fine print and infects your computer when you give into recklessness. Don’t make that mistake. Your diligence is the key! Even a little extra attention can spare you an avalanche of problems. So, don’t be lazy. Always take the time to do your due diligence! Don’t visit questionable websites. Download software and updates from reliable sources only. And, of course, don’t skip installation steps. Forget about the “Next-Next-Finish” strategy. When available, use the advanced/custom setup wizard. Deselect the unwanted extras and go through the terms and conditions. Don’t hesitate to abort an installation process if you notice anything suspicious!
