One last thing i wanted to point out cuz alot of people get hacked over this thinking its "safe"
never download a patch outside the downloader
alot of people add keyloggers and such to torrents cuz people want to download a patch faster, and this is where they get it from
Please don't spread bullsh*t like this.
Even when you download the patch file from somewhere else its still checked by SE's patcher to make sure it matches the proper file. The amount of work it would take to modify the patch file to contain a virus and get it past the file check on the downloader and somehow have SE's patcher install the virus would be beyond ridiculous.
You're assuming that everybody knows exactly what to do to manually patch the game. I could easily upload a Trojan (if I had one) named something like "FFXIV_Official_SquareEnix_Update.exe" and tell people to patch all they have to do is run it, and I guarantee that a few people WILL download and run it.
So the warning IS valid. If you don't know **exactly** what you're doing, use the built-in patcher and don't risk it.
And to the OP, ask yourself this question (don't post it here)- Did you use a STRONG password? If it's not at least 8 characters long, containing both upper and lower case letters and at least one number, it's not that strong of a password. If it's a word you can find in a Dictionary, or even a mis-spelled word, name, or combination of real words, that is a VERY WEAK password.
If you used a weak password, someone probably guessed it using a Dictionary attack, and as long as you don't see anything strange on any other online accounts you might be ok.... just make sure you change ALL your passwords.
But if you want to be SURE, then you need to wipe your system clean and re-install your OS from scratch. You DO have your data backed up, right? RIGHT? Hope so.
Ya, it's a pain, but it's better than someone running around with passwords to things like your bank, etc.
Sometimes it's better to be a little paranoid than assume you're safe, even if there really isn't anything to worry about.
