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?
