The trojan horse is called Mac Defender. It's a web pop-up containing a spoof message that tells customers their machines are infected by a virus and they must install anti-virus software. If customers agree to install the software, the program sporadically loads porn websites on their computer.
Sheesh, and here I am, like an idiot, loading them all manually.

But seriously, this is why I have AV on my iMac :agreed:

This has been going on quite awhile now. While it's officially unsupported for Apple to help people with removal of it, there are many posts on their discussion forums that can tell you how.

I honestly don't understand why OS vendors aren't baking virus protection right into the OS. Microsoft has MSE, but it doesn't ship with Windows.

You get an antivirus program completely for free from an ad that just "pops up" on your computer? Anybody know how I can get my computer to do this? That way I won't have to worry about viruses ever again!

I've got Sophos anti-virus which has been rock solid so far, and the only suspect things I've found were a few dodgy javascript files.

On the other hand, I'm not a fucking moron, and I close pop-ups, not download whatever they tell me to.

Sometimes I wish people felt physical pain when they get a computer virus. They'd all stop being so dumb then! :lol:

No, it doesn't. You're thinking of the Malicious Software Removal Tool, which isn't the same as Security Essentials. MSRT only runs once, it doesn't run in the background.

It appears you actually, actively need to install the thing for it to get to your system. I'm not at all worried, and I'm not going to install any antivirus software. I have precautions that I take, like using a user account with restricted privileges (Standard account), and I avoid third party software that doesn't come from a trusted source.

Yes....but you can still be the guy with AIDS at the orgy.

Mac users can pass malware onto Windows users.

Don't get me wrong, I hold no illusions that my system is invincible. :lol:

I just think that, as long as you're using your computer responsibly, the risk just doesn't warrant running anti-virus software on OS X at this time. I'd sooner consider using a separate, even more limited, account for web-browsing (if simply browsing the put my system at risk to malicious code), or even a virtual machine, leaving the host OS disconnected from the Internet and being even more restrictive (or paranoid) about third party apps.

Browsing the web exclusively in a VM is about the most paranoid thing that I can think of :lol:

Why don't you download Virus Barrier Express from Intego for free? It only runs when you want it to, and you could check your system every once and awhile. Same goes for clamxav, which is also free, however it also checks for Windows viruses.

Additionally, browsing from a VM is great, but you can't disconnect the host from the Internet, since the VM has to pass through the host to get to the Internet. The only feasible way of doing that is to run it in bridged mode, set a firewall rule to disallow outbound http traffic on the host's IP, while allowing the guest's IP. Then run a Live Linux image off of the .ISO image in the VM, giving you a fresh boot image each time. The attacker would A. first need to know how to breach the OS you're using, B. know that you're running it in a VM and need to know a vulnerability in that application, and C. know a vulnerability in the host OS as well.

EDIT

Also, this is a simply retarded situation. Don't give your password if you're not purposely installing something, simple as that. The best an OS can do in this case is block certain signatures from apps being installed, but even then it's a cat and mouse game. No OS is smart enough to know if an app that you willingly install with your user credentials is malicious. If it did, it wouldn't have let me install MS Office for Mac. :D
