Help needed with AntiSpyCheck Alert

Does any one know how to get rid of AntiSpyCheck Alert programme which seems to have infiltrated my computer since five o'clock today, I have scanned my computer with Zone Alarm and it found 3 viruses and 7 spyware, but it hasn't said anything about AntiSpyCheck Alert. I have print screened some of the messages (just now another one appeared) if you need to see the messages, when I try to delete the programme it tells me something about admin, also Google is telling me that something is changing my internet settings, please help, also my computer is running soooooo slow. :mad: This programme is also making me go on the internet to pay for the full version so that I can get rid of my "spyware/trojan" and every time I try to turn it off on my task bar it tries to open the internet.
