Hello, I went to download MTA and I noticed the link being a little funny after I downloaded and installed. It seems to work fine, my av did bring up a notice about something being wrong with the file but it was installed and worked fine. But my question is is why is there two links? Both have different download links as well but are the same version. I thought I always downloaded it from here: https://multitheftauto.com/ Google comes up with this: http://www.mtavc.com/ Whats the difference and should I be worried?
