    Straight off the bat I do want to say that I do tend to DL songs and videos via torrents with no problems, but 2 days ago I downloaded an Apple program off a torrent as well and it wasn't iWork or Photoshop.

    Okay, so during that day everything was fine. Yesterday, I try to export video from my EyeTV solftware that I captured from my PS3 using the Hauppauge HD-PVR which was fine. I then tried to export the same video to H.264 with no re-encoding and the exported final copy was corrupt - won't play in QT or VLC .. audio is not in sync, and the program shuts down.

    Never did that before so I can't compare. Today, I try and export the same video straight to iMovie HD like I have been for weeks and now those video files are skipping every 10 seconds. The same thing happens if I export to HDV 720P or straight to Mpeg-4. I've been doing this for a while and just today this started happening.

    THEN .. I go on YouTube and when I go to watch a video it says, "Hello, You might not have the latest flash player installed, click here, etc etc" I was just watching YouTube videos yesterday! So I installed the flash player, did some Repair Disc Permissions, deleted the torrent app that I downloaded Friday, restarted -- and it's still the same.

    Does this sound like a virus?

    It doesn't sound like a virus to me at all. What program did you torrent recently?

    iLife, iWork and Photoshop are all known to carry OS X trojans. Anyway I have no sympathy for thieves.

    No doubt Tuff.

    Anyway, so if it's not a virus .. does this behavior sound like anything? Why would YouTube suddenly require me to download the flash player again?

    Well I hope this is a learning experience for you...

    First thing first... You CAN NOT have a Virus(well you could be the first I guess).
    You could have a installed a Trojan...

    You can try a couple of things but your best bet is to Zero the drive and start fresh.

    First is,

    ClamXav
    http://www.clamxav.com/

    However if it finds a Trojan and you remove it, it doesn't mean you are safe you could still have all sorts of nasty things running around on the system like key-loggers, root kits, etc.

    Second thing to try is,

    OS X Root Kit Hunter
    http://www.christian-hornung.de/

    I will say again if these do find anything you best option is to re-install from scratch.

    Edit:
    After you do those things Install a program like Little Snitch to watch your connections to make sure you don't have any strange programs sending/receiving any strange data.

    not iLife. All I see on popular torrent websites are legit rips.

    Really, ClamXav is useless for Mac viruses.

    I recommend the OP to install iAntivirus and run a full scan,

    And..

    iAntivirus will be 100% useless at finding anything if you don't have an intel based Mac because it won't even run...

    Ok then, the OP can just install a trial of some commercial antivirus and run a scan.

    Yeah I installed Clam and it found nothing anywhere. Guess I was just being paranoid.

    Thanks fellas.

    ClamXAV does not detect OS X threats.

    About the torrented FCE4: I'm 99.9% sure that torrent is clean.

    iAntiVirus: I have a feeling that it does not detect threats that have already been installed - it just detects the installer packages themselves. I found this out when I ran a scan on a system with a keylogger installed - it only detected the installer package, not the installed keylogger.

    I emailed PC Tools (they make iAV), they fixed the definitions for the specific keylogger I mentioned, but I'm not sure if they have fixed the definitions for the other ~100 threats they have listed in their database.
