Thanks for your warning. I hope you prevented people from downloading fake wallets.
This is the only official ANN (nº 1 of your links): https://bitcointalk.org/index.php?topic=5128919.0
2 and 3 were phishing attemps.

I am sorry to answer on this old thread. It is on the first google positions, therefore, I had to answer in order to clean our damaged image.

CatalansCoin wallets were compiled in my own laptop, there is no virus here, nor the wallet ask for Administrator rights. Those threads are people impersonating us. Im sorry that some people lost ethereum after installing fake wallets, but there is nothing we can do.

There is no virus here, but I still decided to delete the first version of the wallet on github. We even already made a hardfork so the first release is useless at this point.

The new wallet hash is 8b634554b6ecd96f732ae83bfe56155e4ab62992df4c53adf76375a8263230dc

This wallet still show false positives on virustotal, however I can assure It's virus free: https://www.virustotal.com/gui/file/8b634554b6ecd96f732ae83bfe56155e4ab62992df4c53adf76375a8263230dc/detection

As I said on the official thread, If you are unsure when downloading a wallet, please check If you are using the official website / github, compile from sources or ask team. Even a file with 0 detections can be malicious.
