I made a rookie mistake with a file I downloaded and as soon as I opened the exe file it just was an obvious virus. After looking into things I found multiple conhost.exe services running in task manager as well as two csrss.exe files running. The 2 csrss.exe files are both running from SYSTEM even in safe mode. As for conhost.exe there are multiple running from my user account as well as one from SYSTEM. In safe mode I only found one conhost.exe to be running and that was running from my user account. When looking at windows process dump I followed a couple trails and found folders within Program Files/WindowsApps (including the WindowsApps folder) that I couldn't not open as an administrator. Ownership was given to certain unknown accounts with SID's that didn't match any of the accounts showing up in powershell with the following command: gwmi Win32_UserAccounts -computername"." -filter "LocalAccout=true"

So I have accounts that I know nothing about able to read write and execute sensitive files. Can I assume this is the work of a virus?
