New Trojan

As i was working on word documents the other day, i came across a very peculiar document transformation. The work i was doing required me to save it in a flash drive which i did but when i went to open it from an other system the document was no longer a .docx but it was a .exe. i managed to scan the same drive with a different Anti Virus and that when i realized the document were infected by a Trojan by the name of “Trojan.Win32.Swisyn.Cbhx”.
If you have come across this kindly share how you solved the same.
Thank you.
