Could I have some sort of bug or virus?

[AC Question]

Some sort of bug or virus.

I'm using Android Lollipop 5.0.2 and i recently noticed that when i turn off my device with some apps running in the background, these apps are still running after I restart my device in multitasking view. I don't think its a bug, must be a virus or something.
Please Help !

Re: Some sort of bug or virus.

Powering down the device just put it in sleep mode (hibernate mode). A snap shot of your system is saved and when it comes out of sleep mode it will be as it was before. You could physically close those apps, but then why.
