Weird Thing happening? Or not?

Ok so, i go on my iphone to search something up in safari and when i do… Most of the sites say " this may harm your computer". I don't know why it says that but it never happened before? Its really weird please help or explain?

Mind generally wavers when it is in utter confusion. Confusion does not occur on its own. It has chain reactions. First we get doubts, which turns into confusion. Then we suspect. All these put together results in fear. When we're absent minded and when deliberately unsettle our own mind in such critical situations like this, in a careless or negligent manner, we're not able to use our discrimination powers wisely, which results in weird things happening. Everything is within our capacity and capability. It is all in our hands, mind and heart. One should not approach such vital issues halfheartedly. As you say it is either this way or that way.
