Please, I dont know much about computers, but today, discussing in a legit website that uses disqus (commenting software) I noticed that a guy was posting photos of some users of that website, he was bragging saying "you have no idea about my profession, you don't know how much I can do with your ip address, I know a lot about you and you know nothing about me". I had a little fight with him and now I'm scared he can reveal my real identity and start posting pictures of my facebook.
First of all, I use windows 8 in my 2 computers, one of them using avg premium and the other one avg free. I have windows firewall on in both computers. I haven't downloaded anything from anywhere, only from trusted providers, never clicked any links from him or anyone in that website.
Now I'm worried because I have a static ip address and I don't know if he can get my ip address from disqus comment sections (he is not a moderator, just someone who insults everyone). This website is a news website, so the moderator are the ones who own that website.
So there are a lot of things going on in my mind right now because I am not the only one using this ip, also my family, I'm worried he can hack into my router and see all our information and start posting them online. Also, what if my pc is secured but the computers of my family members are not too secured? can he hack them even if they don't even know of this website nor of this guy?
I know some of you may say, he is a troll, but how he got the info of the other users? how could he possible get into their facebooks if they don't use their real names? I also scanned my 2 computers and no virus was found, please help me to get this clear (btw i already deleted my account and all messages from that site) but I'm constantly checking his profile to see if he has posted anything about me.
