I do ... and I am extra super lucky that my cousin is such a genius. I've been having sooooooooooo much trouble with my CompactFlash card, and haven't been able to retrieve a single photograph from my camera.
Turns out it's a particularly nasty virus, and my very clever and patient cousin spent a very long time on the phone with me helping to fix it. He's also going to clear it off my memory cards (and I realised it could also be on all my thumb drives!). The down side is that I also passed the virus onto my laptop and my mother's laptop. Still ... he showed me how to remove it, so I'm crossing fingers that I can read my notes and get the job done.
So the moral of this story is to keep your anti-virus software up to date, and ask everyone you meet if they can help you with your computer problems until you find someone who says yes LOL.
