Hello, Csrss - cannot end this process in task manager so I searched it and I cannot delete it it says “Cannot delete csrss: Access is denied Make sure the disk is not full or write protected and that the file is currently not in use.” What do I do, I know it’s a Trojan of some sort. The folder is in C:\WINDOWS\System32 jess

Who told you and how did you verify it's a trojan ? Do not type anything in this space.
