Stop an unwanted programme

Yesterday I started to get a programme which keeps on popping up and I can
not stop it. It is http://auth.microbillsys:1003/3/isvalid.php. When this
appears my screen goes blank and I can not find a way to stop this. Can
anyone help?

MicroBillSys Removal Guide

What is MicroBillSys? (Run MicroBillSys check with SpyHunter)
MicroBillSys is a nasty application that is associated with several
pornographic websites, including www.Sexxxpassport.com, www.Mysexworld.com,
and www.Membersmatter.net. Once installed on your PC, MicroBillSys will
persistently prompt you to buy a membership to these sites. You will get a
three day "trial" period, but when it ends, the program may also lock down
all Internet access unless you pay the membership fee.
