A month ago, I was infected with this trojan. The file was in a "Super Metroid Level Editor" folder in the documents folder; I've placed it there long ago and never used it. The file in question (SOLA.exe) has been in there ever since 2013-2014, yet I've seen no issues until June. It kept enabling the C and D drive sharing option. Thankfully, I've noticed it pretty much every time and quickly disabled. I've noticed no other changes, other than most of the System files having a different modified date, might just be a coincidence. Windows Defender detected and removed the file on 6/19.
I feel like I'm being paranoid, but can anyone tell me what else this trojan does?
