One of the voting sites seems to tell me that malaware has been detected. Cant remember which one to be honest. But it still gets me 20 CP's as it is one of the backward incentives. As long as i get my daily diet of CP's i dont really mind! :)
In order its the first 20 CP vote (the one that looks like a dragon on it), you can click on it and vote. When you vote you get taken to a warning screen about malware and ask if you want to continue (at least on Chrome). I've just exited out at that point and I don't catch anything and also get the 20 CPs. Probably another hacker attack, it should blow over soon.
