Bitdefender SQL Injection Block

So, my Bitdefender Total Security just told me that a SQL injection attack was attempted by this site and blocked it.
 
I added the site to my exceptions, but you guys might want to look into things to make sure you haven’t been hacked or something.

Does it even realize what an SQL injection is?..

It usually does a much better job at detecting actual threats, so I don’t know what happened here.

An SQL injection is when a hacker attempts to abuse a bug in a site (the kind which derpibooru dev team actively looks out for and we are confident we have none of those) in order to, through bad input, manipulate the SQL query used to save or fetch the data in a way where they can damage something or alter data in a way that was not intended by the developer.  
This is a server-side attack and no antivirus should be able to detect that on client-side, unless it actually detected something else and the error was very unfortunately named.
 
What I’m trying to say, derpibooru is safe, check your computer for viruses with a different antivirus, as your current one might have detected consequences of another virus that it failed to detect.

@Meow the Cat  
Seems to me an antivirus could, in principle, fairly easily detect SQL injection attempts by just sniffing query strings as they’re submitted through browsers, although how it determines which site to blame puzzles me.

@Wellwater
 
It happened WHILE I was on this site, so that’s probably why.
 
And I did use my antivirus scan and it didn’t detect anything.
