Causes of SearchProtocolHost.exe errors

This is partly associated with the Windows Search service. It is an authorized Windows Update which comes down when you perform your regular updates. To make this service stop using all your CPU you need to stop the service from running.

Quite often, this is due to a malware infection. Trojan:Win32/Urausy.E is a highly dangerous malware infection and it will download many trashy and malicious files on to a PC system and makes it corrupted. What this Trojan often does is to open up a backdoor for internet attackers remote accessing to your PC. This has been a traditional trick for Trojan creators. Computers that are infected by Trojan will have their system settings altered, will suffer from reduced memory and poor system performance due to Trojan's ongoing processes and may even be subjected to rootkit-based attacks.

Although the exact symptoms of a Trojan infection may vary, in most cases, Trojan will reveal its automatically-launched memory processes in the form of randomly-named .exe files, such as SearchProtocolHost.exe. When you find this Trojan in your computer, you must remove it as soon as possible.
