Some friendly NPC to attack me (The Elder Scrolls 5: Skyrim)

I have this problem - some friendly attack on me for no reason, the legate Rikke attacking me, even though I hadn't done anything and even the storyline of the Empire was, in riften attacked by some NPC or just be hostile, saw in riften some man abruptly became hostile to everyone and it just beat the guards in Whiterun attacked me grandmother of the gray-manes, in its vicinity was attacked by a man, who can buy a horse and when I killed them I didn't give a penalty, what the fuck? Fashion endured, the game started, who knows what's the problem?
