My QQ was poisoned in the Internet cafe. After returning home, I often send some yellow talk, messages and comments. What should I do?

For this problem, just change the password. This is a worm virus, because you play DNF, you must have a secret card, that is, the other party will not steal your QQ, and hackers just log in to your space to post information, so you only need to change your password, and then don't open the webpage casually in the Internet cafe, many of them are fishing, that's all!
