This is quiet funny, because you are 100% infected with a virus. How would you know that you are not? Malware that does obvious bad things like cripple the machine or encrypt the drive is minority. But it's actually not funny, it's dangerous. This behavior endangers others. Likely your computers have been a zombie in a botnet for many years - I'm always wondering how these large botnets can exist at such scale. This is why one day we all will not be allowed to use computers without a "driving license".
