Lastmedias.biz is an untrusty website designed to deliver advertising content to users' computers directly. Most users do not open such pages intentionally; rather, they get redirected to them by corrupted advertisements on the Internet, an adware program installed on their computers, or a browser hijacker that has modified the settings of their browser.
Lastmedias.biz displays to its visitors a fake error message claiming that the users need to click on a "Download" button to proceed with the download of some file. Yet, clicking on the message gives the unsafe page permission to deliver advertisements to the user's computer. Lastmedias.biz typically promotes online gambling sites, pages with adult content, Potentially Unwanted Programs (PUPs) and other harmful tools and files.
You can delete Lastmedias.biz's permission to send you notifications manually; however, if your device is infected with an adware or a browser hijacker, we recommend using an automated malware removal tool. Such PUPs can be a severe threat to your online security, as they typically have data-tracking features that can lead to extreme financial losses and even cause identity theft.
