Laptop free cleaner

Just got a laptop and not very good with it yet. Is there a good antivirus/hardware cleaner I can use that’s not expensive? Thanks

A quick search rendered this:

If your new laptop has Windows 11 on it. It comes with a built-in antivirus and cleaner, that works good. I have not bought an antivirus for my computers. In years.
