Canada Police Cybercrime Investigation Department Virus

So I was surfing the internet today when this thing pops up. (Not the exact same screen as the one I saw but almost the same)



At first I was terrified that this was a real thing but then I noticed they wanted me to send them money over the internet, and this made me suspicious.

After restarting my computer couple of times I managed to get back to my desktop, and look this up and it is in fact a scam. The guys who made it seem to have made different versions of it for different countries and its a worldwide thing.

Apparently its some sort of Trojan that can get past all the major Anti-Virus software programs (including Norton). I've been looking online for awhile on how to remove it but different websites have different instructions, and I'm not sure which ones are supposed to be for Windows 7. I'm not even sure how to tell if its still there or not.

Has anyone run into this before and can tell me how to tell if the virus is still on my computer and if so how to get rid of it?
