Hi I will send a warning, my son the other day got his steam account hijcket by a chat recuest, which contained a link to a page: steamcommunity-freenvidiagames.tk if you receive an ichat recuest with that link, do nothing just deny it or delete it because it is a link to a page where they can steal the information to hijack your account. or even better
take a screen dump of the message as i did, and send it to Steam support so they keep focus on the problem. is ure hope they will wake op soon and help my son getting his account back.
