I think my sigma sd14 has a virus. I just got it, it's new. Then I connected it via usb to my pc WHICH i forgot is extremely infected by virus. Now everytime i access my dslr it wont ON if my memory card is in it. What do i do now?

Your camera requires service, this problem will only get worse.

with the flash on, I would think most pictures would be bright white. Try turning the flash off, use a different setting than P.

The best way to download pictures from your camera to your computer involves removing the memory card from the camera and plugging it into a card reader (either built-in to the computer or connected via USB or FireWire). This is likely to be faster than connecting the camera to the computer, and won't run down your camera's batteries.

Once the card is plugged in, it will appear to your computer as a removable drive. You can use the operating system's drag&drop facility to copy pictures from the card to the computer's hard drive. Or you can use any photo cataloging program, such as iPhoto.

Hi Paul yes that lens will work on all sd sigma cameras even the new SD1

ur philips mp3 player memory is infected by virus thats why it cant be detected by ur pc same prblm happens with pen drives as well.

If the lenses were for the Sigma camera, then unfortunately, they will not fit onto a Nikon camera. Sigma makes lenses for various different mounts; the operative word is "different."

No. You can buy an adapter to fit a Nikon lens onto a Canon, but not a Sigma.

This Sigma has poor reviews at high iso levels i.e 1600, try dropping the iso levels down and see if there is any significant improvement.

Is your antivirus updated? Always make sure to update your antivirus.

Use a clean PC and download a virus removal tool for the specific virus that infected your PC at http://www.symantec.com/norton/security_response/removaltools.jsp

Put your virus removal tool (or tools) into a CD or USB thumbdrive then insert it into your infected PC's USB port.

Commonly, you can boot via Safe Mode:
- press F8 key on your keyboard while the computer is booting
- then in the boot menu, select "Safe Mode"
- browse to your CD or USB drive and run the virus removal tool.

However, it is much more advisable to use a live CD tool like MiniPE and scan your PC to remove the viruses.

check to see that if ur USB has infected with virus or scan your pc. let me know
