Please see this thread. Appears this could be normal behaviour.
Processes Becoming Suspended
Example the SearchUI.exe. Click on Cortana with process explorer window open. It should jump right back to life. I had three suspended. I didn't used Cortana after opening, click somewhere else and now it is showing suspended again.
With you could also click on Photos and see if it wakes up.
To the OP: According to some AV tests Qihoo's 360 AV real-time protection is not that strong. Tread with care. 360 also tends to throw quite the false positives at user. By all means I am not saying it's a bad product or something like that, but be careful. A friend of mine using 360 was hit by a ransomware virus.
