Pulled this directly off the subreddit soon as I saw it. I'm sure plenty of you are well aware but I'm posting this for the hunters who don't necessarily see the latest info about the game,

Long story short: Many users of Thehunt.tk are getting malicious adware infections and reporting their infections via the post at https://www.reddit.com/r/ffxiv/comments/3dph96/psa_thehunttk_is_infected/.

If you regularly use TheHunt.tk when you're hunting for seals, make sure you run Malware Bytes or another adware/malware scanning tool ASAP. Some folks are suggesting the program here: https://toolslib.net/downloads/viewdownload/1-adwcleaner/ for safe removal of the infection. However, I have no personal experience with the second tool so I hesitate to recommend you try that first.
