System-scanning.xyz is a dubious website that is created with the sole purpose of propagating browser-based tactics. Most users do not land on it willingly and are instead taken there either through redirects from intrusive advertisements or as a result of having adware applications lurking on their devices.
A System-scanning.xyz visitors will be presented with one of several different schemes. The website might attempt to trick them into subscribing to its push notification services by generating numerous fake alert or error messages that lure users into clicking the 'Allow' button. Doing so will provide System-scanning.xyz with the browser privileges it requires to start exhibiting unsolicited advertisements to the affected device directly. Closing the browser after having already fallen for the tactic will not be enough to stop the advertisements from appearing.
System-scanning.xyz also could be running a different tactic where it tries to generate revenue by abusing legitimate commission programs. The website displays a window designed to appear as if it is coming from a legitimate anti-malware program. A scan is then allegedly conducted, with the result always being that five malware threats have been detected on the user's device. System-scanning.xyz will urge users to update or renew their anti-malware subscription by taking them to the legitimate Norton website. Users should keep in mind that no website can perform scans of their computers.
The best way to deal with System-scanning.xyz is to ignore it simply. However, if the redirects reach abnormal rates, you may want to scan your device for any potential adware applications that might have snuck onto it.
