Their downloads may be packaged with malware, adware, trojans, and many other bad things. This is a recent change. Optifine is a tool available for java minecraft which provides more festures and better control of the graphics of the game and provides for the use of shader programs to change the visuals of the game

Optifine offers many graphical improvements without using shaders but when using shaders the game can take on a whole new view.
Optifine.net has ads in order to keep up it's development, but they often are masked as download buttons
Be aware of these suspicious and beautiful boxes, because the actual download link is a plain blue text. I've always known optifine doesn't go along modded minecraft Because the most recent version of optifine available is for 47.1.43 and that's a review version, so no you cannot use optifine and forge for any version of forge after 47.1.43 and even if you do downgrade your forge to accommodate, some 1.20.1 mods are incompatible with it, i found that out trying forge 47.0.35 most good 1.20.1 mods like aether and twilight forest need 47.1 or higher to work. Any executable jar file can harm your computer
This is a generic message that you get from trying to download nonstandard executables like jar files As long as you downloaded from optifine.net, you're fine. After a few hours of trying to fix this, i realised i wasn't on the version of forge that the most recent 1.18.2 optifine was on. Optifine has been a thing for well over a decade now, and most players know what it is
The only thing i kinda miss is the zoom from optifine there is a mod called zoomify, it has a setting which mimics optifine's zoom 1:1 (+ a lor more optional settings, like zoom scrolling)
Double click the optifine jar and it’ll give you an option to extract, this will extract the optifine mod that’s meant to be placed in the mods folder
