Does fiesta have a virus

Answer 1

Technically yes, but it can be removed.

Many people have reported finding a virus after uninstalling it. It can be identified as a Trojan by many Spyware categories, but some players claim that this is just a memory leak from its folder in the first place, and shouldn't be taken seriously.

I believe that it does, in fact, have a virus that is able to evade several anti-spyware detections, but can be removed with the right spyware cleaner, and you also have to delete the remaining folders and pretty much everything having to do with Fiesta Online after uninstalling the game. It's possible, but it's up to you whether you decide to take the risk or not.
