looks like a program that boots with windows is looking for that file and cant find it, try disabling all start up programs that arnt needed
that file is a virus (or was) as csrss.exe shouldnt be in a temp folder. You should run a anti-virus scanner if you have one and see if it picks up anything else. You can remove that startup entry by clicking on start and typing msconfig and remove it and any other dodgy looking files from the startup tab
Thats good. If you're unsure about any entries under the startup tab, you can just post a picture here and im sure someone can fill in the gaps.![]()
Did you run Malware bytes in Safemode? I would even use CCleaner to scan the reg and let it delete this entry altogether.
