You may want to rescan your system. I don't have a virus on mine. mine is clean, or yours is showing false positive.
The best thing for you to do is download the entire game again, and then put your saves back into the proper directory. Using the old .dll file may give you problems with the triggers in the game.
the virus did trigger on the file you did upload.
the one i have from 0.12 is fine.
and the one that had to be in 0.14 wasnt there, so i guess it was same modified as yours (maybe cheat enabled or whatever other mod type) so probably antivirus did remove it and thats why game did not load past unity screen.
or yours just doesnt trigger on your pc now bc you set it as trusted/ignored on your antivirus ? dunno
i had to disable antivirus, then set the file on ignore then run antivirus again, then could test. with enabled AV couldnt change it, bc its literaly instantly deleted as it unrar's
also. different AV behaves differently, some things that avast goes crazy about comodo doesnt even warn, and vise versa (comodo is smarter than most AV, including kaspersky. in 99% cases)
so this file probably has a script or part of script that matches some known T10 trojan script maybe.
low lvl threats comodo do not remove instantly, but just warning and ask for action, here it just show that t10 trojan removed right after i unrar it,, it barely could flash on desk and disappears.
PS: why would ned to move files when download new game?
this game saves on appdata and is automatically availible to new versions. didnt have to move saves in this game.
