Awww, you were "this" close to actually posting a useful informative video that I could compliment you on.... then you brought out the "hitman pro" stuff again. If you'd left that horrible, system killing app out of this video you'd have had a winner. Please ppl for the love of God (or your PC, whichever you prefer lol) do not install or use this program and certainly don't pay anything for it. It will do nothing at best and more than likely will actually break your machine. Other than the crappy pointless app your promoting, the rest of the advice is at least solid useful advice. Although it won't actually guarantee your system isn't hacked as those things don't show up in your task list or installed programs so can be hard to spot. But if your machine is suddenly much much slower or your computer is all of a sudden using a lot of bandwidth (and it's not windows update) then you might have issues.
Update windows sometimes Microsoft will send mrt tools update for you 😅 also try optional updates given by windows in advanced options of windows update
