When I tried downloading Optifine I got a boatload of malware and content such as that on my device (it's all scanned and deleted now, THANKFULLY) and hopefully this WON'T cause anything.~

For some reason, my Optifine wont open... I downloaded it, put it on my desktop, and tried to open it and nothing happens. Literally, I click on it and NOTHING happens and eveything goes back to how it was 5 seconds before it. Any help? I want to be able to participate in Reddit UHCs without lagging and dying everytime.

I'm having the same problem. I have downloaded it, tried putting it in folders, tried using forge, renaming all the files to optifine, everything. I cannot get it to open, install or work. I even did all this after completely re-downloading Minecraft.
