Hello. I was thinking about buying a license for this product. I would really like to get a lifetime license, so I would never have to worry about re-purchasing after one year or two. I stumbled upon this site: hxxps://www.deucesoftware.com/Malwarebytes-Lifetime-License but I am not sure if this is legit. I have heard that if you purchase licenses from other vendors, and something goes wrong, it might be an issue later on to fix it. Any inputs on this? Thanks!
