Forenote for owners: Please move the thread to its proper place if it doesn't belong here. But I felt as if this was worth mentioning, and therefore I've put it under Minor Announcements for the time being. But now for the interesting stuff...

Introduction
So to start it off... as some people know, I'm a real nerd when it comes to Discord - I'm on at least 50 major servers, including bot servers, Official Discord servers, and even servers like CatsCraft's. This morning, I was pinged twice by servers I wouldn't usually be pinged on at all, both for the same reason, which regarded the usage of OptiFine. Both of them simply said one thing: the OptiFine website had pretty much been compromised, which too has affected the website's downloads.

What is OptiFine?
OptiFine is a client-side mod (of which can either use Forge or not) for Minecraft that is used for many different purposes including:
- FPS increasing
- Easy usage of shaders
- Provides several options to make your Minecraft experience smoother and cleaner than the game itself.
- May apply to some people - if you're like me and experience issues where the game freezes suddenly, OptiFine doesn't do that and fixes it.


What if I use OptiFine?? Should I be scared?
No. If you use an old version of OptiFine, there's a very good chance you'll be just fine; HOWEVER - do refrain from downloading a newer version of OptiFine for the time being.

Remember that when I mean old version, I mean you downloaded the jar file for OptiFine a good while ago, I'd say from a week to a month ago. All versions on the OptiFine website in question are in fact infected.

If you have downloaded a new version of OptiFine in the past week or so, chances are you've been infected - in which case delete OptiFine instantly and scan for any viruses/trojans to ensure you're safe.

EXTRA NOTE: People have started saying it was the ads causing issues, however, someone did say they managed to get a trojan virus. Until the website is officially clear, please still refrain from downloading from it.

What proof is there that this is real?
Well firstly if this turned out to be a copypasta, I wouldn't be writing this right now.

Secondly, there is a good amount of proof from the Reddit (/r/Optifine) community, the link here: https://www.reddit.com/r/Optifine/comments/7wa18a
Thirdly, I did try to go to the Optifine website myself, and because my antivirus is a disappointment, Google stopped me from accessing the website instead, giving me something scary that looks like this:
When will I know if it's safe to download from the Optifine website?
As I mentioned before, people have started saying it's the ads, not the downloads - HOWEVER, that doesn't mean you should walk into the website oblivious of the risks still involved. This was what one of the Reddit users said:

Edit: Apparently it came from the deluge of tricky adware downloads Optifine now flings at you with the new launcher. Also, it takes multiple sweeps with Malwarebytes to clean out of your system. Fun stuff.

When it's safe to download from the website, either another user or I will update the thread.

Any other questions I will respond to the best of my ability. For now, yours:

P.S: Happy Early Valentine's Day. :sneaky:

Thank you for warning us about optifine. Also I'm positive if the Optifine Jar is NOT the jar symbol and is a grass block. Remove it asap, because that too is a virus. I feel for that once i started playing mc.

Best rule of thumb is to scan each and everytime you download something and to scan everything; even stuff that you know is (or should be) safe. A lot of anti-virus programs now can be setup to scan a file before it is actually written to the HDD.

Or simply use the next best anti virus: our common sense. ;)

As an extra note yes, whether HDD or SSD, some antiviruses do check a file before it's written. Or in fact it can come as a browser add-on (which is how mine does it).
