Everytime I try to log in to Steam,it keeps on treating my Log-in as if it was from a new PC. Truthfully, I did have a huge fight in a forum with somebody in Europe(I'm located in S East Asia) and that person swore revenge but he gets access to my Cookies by hacking in just one day? I'm not joking since I seriously consider that may be the only reason since nothing like this had happened before. Now I'm too afraid to even play my games on Steam. I did do some searching and read some online tips on how to deal with the situation but that online question was asked by somebody else in 2015 and the explanation was that something is deleting the Cookies slowly.
