I have a trojan on my iMac, how can I remove it?

Well that's the problem, it doesn't appear in the extensions tab! I installed it, but I don't find it anywhere. Even though it said it successfully installed.

Also, I installed a Java plugin earlier, and I just read that there were some issues with that not too long ago. Apparently there's a test where you enter something in terminal, to check if you're infected, and apparently I'm not. But it might just be another issue.

I thought I had solved the problem now, because I had changed the Safari home page to nothing again, and removed a few things. Obviously I knew that it would still be hiding somewhere.

And yep, I just restarted Safari (I'm writing from Firefox now), and something set the homepage again to the site I mentioned earlier.

PS: I have still tried to turn of all extensions. It doesn't seem to make a difference however. Earlier I had done this as well and I had turned off plugins too in the security menu. It seemed to be gone, even after restarting after some time, but now eventually it came back. It's gone again now, but only because I changed the home page. It isn't really gone actually, and it will eventually reset the homepage to that site in some minutes or so...

@ etresoft: Well, I downloaded it from the official Java site, so I supposed it should be safe! And by the way, how do I know you're software doesn't contain malware now? 🙂

@ Thomas: I read your article and removed those internet plugins. I also removed anything Java related, or at least I believe I did. I didn't notice anything suspicious in the internet plugins however. I'm still bothered where this "Youtube downloader" plugin has gone. I mean I've installed it, it MUST be somewhere...

If you want I can send you that DMG file, in case you think you could analyse it somehow? I still have the site I downloaded it from somewhere in my history, it shouldn't be hard to find it. But I don't want you to get infected as well, so I wouldn't open it! Perhaps you can analyze it in a way without opening it however?

For now however, Safari seems to work. No more redirecting. Java is allowed, so are plugins and also extensions. I'm still worried that the thing is hiding somewhere in my computer and that it may get hold of private data.

I've run an app called VirusBarrier express earlier (downloaded from the App store, should be safe!), it scanned by whole computer and didn't find anything. But then... it may not have found anything because this isn't a virus, right? Do you believe it can found trojans or other malware?

@ etre: I've still run your program and don't think I've noticed anything suspicious! I don't want to post everything on here since it also may contain private data (I saw an email address) 😉 so maybe you can tell me what to look out for? There's a few things where it says "failed" but I've had these for ages.

That's exactly what it is! You know what's funny? Before I downloaded it I was surprised that it was downloaded so many times, but nobody gave a review yet (as opposed to the other plugins when you search for "youtube").

As a joke I thought it must be a virus and everyone's computer is dead now, so they can't give a review 😝

edit: I've restarted my computer now and Safari still works. Nothing suspicious at the moment.
