From what i see on virustotal i would not recommend it ti install the wallet , for sure there some false positive detections as it looks like that there is a miner integrated,
but there are also some shady detections like ,
Win95.Marburg .
When Marburg is executed, it is decrypted and searches for .scr (screensaver) and .exe files in the current, Windows and system directories.
In some files, Marburg overwrites the code at its host entry-point with a block or polymorphic code, though depending on the structure of the file, it may not.
It sometimes appends itself to the last section of the file. File sizes will be divisible by 101, and the virus will avoid infecting files with a file size divisible by that number.

Just my 2 cents here.
