The 1-888-479-3649 Fake Windows Activation Screen is a Trojan Horse that displays a fake Windows Activation screen on your desktop in order to scare you into calling a remote tech support number. These fake Windows Activation Screens pretend to be alerts from Windows that state "You must activate Windows within 1 day to continue using all Windows features".
If a user clicks on the Activate button it will pretend to try to activate Windows and then give an alert that states "Windows Helper is unable To Activate Windows Contact Support To Activate.". This is done purely to trick you into calling the 888-479-3649 number so that they can use scare tactics to sell you a support license. The support link in the screen will also open a browser window to www.supportforme.com, which is used by the remote support company to remotely control your computer via GoToAssist.
This Trojan is typically bundled with programs that pretend to be a free Youtube Downloader, but in reality serve no purpose other than to show you these fake alerts. The installed Youtube Downloader application does not actually enable you to download youtube videos, but rather just executes a program called Box.exe on a timer. The Box.exe program then displays the fake Windows Activation Alert.Without a doubt, this program was created for the sole purpose of displaying fake Windows alerts in order to trick you into purchasing remote support. If you are infected with this program, please ignore any advertisements that are displayed and do not call the displayed number. To remove this adware and any related software, please use the removal guide below.
