This is probably overkill the last step should probably be enough but if you are feeling paranoid:
I think the default on Win 7 is not to autorun but just to be safe get Autorun-Eater
http://www.gamefront.../aesetup2.6.exe
And install it first. It will prevent any autorun from working.
When you plug in the camera card it should tell you what drive it is (I'll call it x: in the following but you need to change x: to whatever your system assigns) and ask you what to do with it. Just cancel out and then Start, All programs, Accessories, right click on Command Prompt and run as admin. Then type (with an enter after the line)
x:
(This selects the drive. The prompt should change to: x: \ --Remember to change this to your letter!)
attrib -r -h -s \*.*
(Makes all files visible)
del \autorun.inf
(deletes any autorun.inf file. It may not find one. I'm not familiar with what your panda vaccine does - probably creates a folder called autorun.inf. You don't need to remove the folder just the file. To create your own: )
mkdir \autorun.inf
(It may say the directory already exists which is OK))
del \desktop.ini
(deletes any desktop.ini file. It may not find one.)
mkdir desktop.ini
(It may say the directory already exists which is OK))
Now right click on start and Open Windows Explorer and find the X: under Computer. Right click on it and tell your antivirus to scan the drive - I have Avast and it shows the orange ball and Scan X:\ )
Card should now be safe to work with.
