ending a malware process does not stop it from restarting also most malware is injected into system dependent process's like CSRSS explorer svchost or other system required or AV process's this is intended to not only avoid detection but also so the victim cannot end the process's with out restarting the system.

OP's Best bet is to either install Avast and run a Boot time Scan or give TRK a go.
its easier to detect malware on a OS if the OS is not in use or loaded ;).

The only reason that I said to look in task manager is because it could've been a send keys script; if it wasn't, Malwarebytes.
