What Is Up2news1.com?
New tabs with the address up2news1.com/rioalz might start to pop up on your browser every 15 (20, 30, …) minutes and then redirect you to random unwanted sites. That browser behavior is caused by a rogue scheduled task that is set to periodically open http://up2news1.com/rioalz/ via the default browser (although you may have more then one malicious scheduled task, and some of them might launch a suspicious .exe file instead of opening the browser, but the results will be similar – new tabs opening and redirecting to suspicious sites). Adware of this type is usually distributed via pirated software and sometimes freeware. You may follow this step-by-step removal guide to get rid of the adware and stop Up2news1.com/rioalz pop-ups.
