How is my laptop faster (better)?

My laptop is actually a relatively good model, but lately it just takes forever for it to start up or start certain apps…

What can I do against it? Is the reason for that all a virus?

Thanks in advance for the answers ^^

P.S.:I use the laptop, e.g. Cut to videos, create powerpoints and surf… (etc)

By the way: I have Windows 10😉

What does the laptop have for internal use?

Oh god sry, I do not know that well, but it's an Acer and there's something about Intel Inside (my dad bought the laptop sry) 😅

Dankeschön😊
