What is x48fly.com?  It is a webpage ‘ad’, which is created for a sole purpose: to display ads or redirect you to another ad-supported webpage. The appearance of webpage ads is a sign that your computer is infected with adware, also known as ad-supported software. You usually get this when you install a free bundled program, that’s why it’s important to be cautious in installing free software and reading license agreements.
The ads vary; sometimes it displays products from shopping sites, fake updates, and worse, the x48fly.com redirect. This kind of program does not delete files nor infect them. It may seem harmless, but once your computer is infected, it modifies your system settings; it can change the default start page and search provider on your browser. It downloads and installs malicious extensions that bring even more pop-ups. While the adware is running, your browser will be filled with unwanted ads. And since your system settings has been modified by the ad-supported software, it enables it to collect tons of data, including every activity you do on the internet, it can steal your private information such as your IP address, what website you frequently visit, links you are clicking and so much more. This puts your personal information at risk, so, obviously, you need to get rid of it as soon as you can.
There are many ways to remove adware; automatically or manually. If you are not quite familiar or well versed with computer, it’s best to use the automatic approach in removing adware: using applications like Malwarebytes Anti-Malware and AdwCleaner.
