I clicked it by mistake but Norton Antivirus caught it immediately, had to reboot the computer but I haven't had any issues since.
Haha, you got lucky! There are some sneaky spies that seem like they are selling you nice antivirus programs, but infact, they actually aren't antivirus programs, they actually let more programs like keyloggers and Trojan horses in, so that they steal your information, without you even knowing about it, thinking that you have an antivirus to block all of it, but instead you are actually weakening your own computer.
I'm using Ubuntu and it wouldn't install.
