Note that many websites have their own advertising, unrelated to adware.
This is an adware program that drops an extremely large ammount of hijacked domains to your the infected PC's C:\WINDOWS\System32\Drivers\etc\hosts directory. These domains are all from the same IP originating in China.
It impersonates a legit Windows file called "SERVICES.exe" to do this. Task Manager will not end the process, you will need to use a third party removal tool, such as X-ray PC.
