Delete Trojan lsass.exe

Specs: Windows XP

In my task manager I found some files. I think they are trojan.
The files are smss.exe, csrss.exe, lsass.exe.(These files are located in D:\Windows\System32) I tried to kill them but it is not possible. There is also SECURE-1.exe. I don't know what is this.

"lsass.exe": Local Security Authority Subsystem Service

If you suspect malware you should run a fully updated Antiviruus scan (I use free Avira Antivirus: )
I also recommend a free Malwarebytes scan:

Also note that : D:\Windows is not the normal place where Windows is installed to by default
Have you re-installed Windows at any stage? It may be a good time to backup all user data and install Windows clean :)
