Start-xyz.com

Start-xyz.com is a questionable website that users are extremely unlikely to visit intentionally. The page could display dubious content and try to redirect to other untrustworthy sites. If you notice that your browser is opening sites similar to Start-xyz.com rather frequently, that could be a signal that you have  PUP (Potentially Unwanted Program) present on your computer or device. 

PUPs often manage to install themselves on the system without the user even noticing it. That is the exact purpose of the underhanded methods that these applications use for distribution. They may be packaged alongside a far more desirable software product and added as a preselected choice somewhere in the installation settings in a practice known as bundling. Another popular method is to hide the PUP inside a fake installer or an update for a product that users are likely to need. 

If you find yourself staring at a dubious page such as Start-xyz.com, the best course of action is to simply close it, and continue with your browsing. Engaging with the presented content could be risky. You may trigger more redirects or pop-ups leading to equally as suspicious pages.
