Canadian Security Intelligence Service Virus - How to remove

Canadian Security Intelligence Service (CSIS) Virus is an application that hijacks your computer in order to get money from you. It displays a message that states you computer is locked and asks to pay 100 USD if you want to unlock it.

Canadian Security Intelligence Service virus targets Canadian PCs mostly and visitors from other countries might see different names. Basically they accuse you for doing some criminal activities, for example, that you are visiting some websites that are illegal, like porno sites and so on. This can confuse many of us, so many people just want to get rid of this and pay without even thinking. So beware that it’s a scam and do not reveal your credit card details under any circumstances. The Warning looks like this:

Attention!!!
This operating system is locked due to the violation of the laws of the Canada!
Following violations were detected: Your IP address is: … This IP address was used to visit websites containing pornography, child pornography, zoophilia and child abuse.

You should be assured, that if this really was the case you would be talking with police officials already rather than seeing such message on PC. Thus it is obvious that this is only a scam and not the real Canadian Security Intelligence Service message.
