I do not think the author had anything to do with this, I think their system got hacked and a malicious file got inserted into the rar. Second of all why would they want to publicize that this file was infected, it would hurt their credit. Someone before me claimed that the files was infected previously, so I cannot be the only one.
I downloaded it over 2 hours ago, and I just downloaded a new file and I am getting same check sums as you, they probably fixed this file on their back end, thus nexus would not show that the files was changed. As of right now the file is clean.
Here is my proof, https://www.virustotal.com/en/file/6d70e8f7a0760ab2be8717ac1ddb50bdb69fd5c55c4afd22b864a3bad34ebd14/analysis/1363931479/
This is no fault at my end, since either they cleaned it up already or it did not effect all servers.
Latest version of uncapper may be a virus, the .dll does not show in wrye smash. If run through virustotal, shows up as a variant of a virus. This may be a new virus that has not be analyzed. Another thing is that this file is a lot smaller than last upload, also last upload if ran through same virus scan does not show anything but this one does. INSTALL AT YOUR OWN RISK.Â
