Why does it say I have SEP (32-bit) and S Service Framework (32-bit) running on Windows Task Managerwhen I had installed the 64-bit version?

Why does it say I have SEP (32-bit) and S Service Framework (32-bit) running on Windows Task Manager when I had installed the 64-bit version? I had installed this on a 64-bit PC and I had read elsewhere that only a 64-bit SEP can be installed on a 64-bit PC.

I fear that this incompatibility may be drawing too much resources from my PC and slowing it down. Please tell me if this is true.

Thanks.
