Stylish rendering with Steam
Updated Windows and Linux binaries and packages are available.
One notable fix is for the "Crisp" Alpha Cutout Anti-Aliasing setting introduce in 1.2 which has been causing performance issues when near fogs or smoke for some players while resulting in crashes for Windows users with Intel graphics. In this release the performance issues have been fixed and the setting has been disabled for OpenGL drivers experiencing crashes.
Linux Steam users with Mesa graphics drivers may have noticed textures being replaced with solid colors once the Steam overlay loads. We have added a workaround to no longer promise the graphics drivers that we are good API-respecting citizens if we detect the Steam overlay so that its naughtyness can go unseen again.
Remove the malware.
Please describe which behavior of Arx Libertatis you think is malicious so that we can fix it.
Most antivirus engines and hybrid-analysis take serious issue with arx.exe and arx-portable.exe, but this isn't the case for previous versions. I didn't look further into why, but here are the Virustotal submissions for it vs a previous one:

We are unable to resolve bugs in third-party software so you will have to take this issue up with the vendors of those products.
We do take reports of issues seriously but heuristic-based malware scores are not an actionable item while being inherently prone to false positives. Note also that the "new" executable you linked is the launcher that selects between the 32-bit (Windows XP or newer) and 64-bit (Windows Vista or newer) variants of the main arx.exe while the old is the main 64-bit arx.exe. This launcher arx.exe is only 194 KB in size, most of which is used by the icon, and I have previously verified that it contains no malicious code. You are welcome to do your own analysis of this file or hire a third party to do it for you.
Oh it's just a suggestion - if some commands or behaviors are triggering so many antivirus solutions (to the point where exceptions must be created to download and run the file), perhaps avoid those if possible since I would imagine lots of people will avoid the mod due to how many AV alerts it triggers.
