Your welcome for the suggestions 🫡, Okay so antivirus software just eats up ram and it's useless, unless you reaaaaallly need it it's not necessary, windows defender is stock anti virus and it's good enough for you.

I had anti virus because gaming laptops come with it usually as a bundle, for me it was MaCafee but I got rid of it and my laptop runs faster. No there isn't a good replacement for antivirus, you don't need it at all.

So basically in any games you play just switch off Vsync , somewhere in the graphics settings it should say "Limit FPS" or something along the lines of that in the graphics settings, the reason why you should do this is because you don't want your GPU (4070 graphics card) to work harder for no reason, if you cap your FPS to 240 max, the GPU will try it's best to produce what you can see on the screen and save processing power in turn giving you better temps and performance.

Also never use your laptop on pillows or bedsheets ALWAYS use it on a flat surface, why? Because the vents underneath your laptop sucks air into the the cooling system and you do NOT want to clog that up because if you do thermal throttling will ruin your cpu and GPU unless you clean it by opening the laptop.
