Windows 10: Wierd changes to my laptop overnight

So I opened my laptop this morning and right after I enter my password and log in to the computer, it restarted and here are some things that I noticed:


- Kaspersky has disappeared from my computer and whenever I try to open it from the shortcut it says that the file has been moved or deleted

- My laptop's fan is running at a higher speed than usual and its a bit louder even when absolutely no programs are active

- At the password entry screen normally there is a different background every time I open the laptop usually of some beautiful scenery, and now its the same one every time I restart

- Also whenever I used to shut down my laptop with wifi on, and open it again wifi is still connected even when I'm not enabling the connect automatically feature, however now, it is always not connected

- I also noticed that there are a fewer icons on system tray other than kaspersky disappearing I cant really remember what were they


All these changes are very subtle except kaspersky disappearing and the fan speed but they are very fishy. Could this be malware? Or is it just a weird windows 10 update? I dont remember it updating the last time i shut down my pc though. Also how do I fix this or find out what's wrong?

2 wierd issues with my laptop??

Hey Everybody,

I have a newer laptop that is a Dell, now I reinstalled windows 10 without the Dell bloat and now when I first bootup I have to hit CTRL + ALT + DEL to get the password window to show up even tho I did not enable that feature in Windows.. I t does not do that on a restart ony when I first turn on the laptop after it has been off overnight.

I also have another wierd anamoly that Bit Locker is installed and was enabled on my drive and I was reading about bit locker it should only be avaialble on Win 10 Pro, I was wondering why it was there and encrypting my drive..?
