I'm surprised they didn't tell you to disable the scan on removable drives.
It's a known bug.
I brought my 128MB thumb drive back home to Singapore for storing some vacation pictures and upon going back to work in China, realized that none of the laptops nor PCS here can read my thumb drive!
I have been using this China-produced thumb drive with no problems on the China PCs and laptops for the past 6 months, and this error occurred only upon my return from Singapore. I suspect that the PC I used back in Singapore had a virus that I inevitably stored in my thumb drive.
Now when I insert the thumb drive, the PC prompts that there is a wrong USB connection. The red light does not even light up on the thumb drive, which means the PC can't even detect it.
Upon checking on the thumb drive problem back in China, an error message popped up as below (I am translating the error message from the original Chinese one):
"Symantec script has prevented a harmful script from operating.
Origin: C:\ -url hcp:\help\+shoot\tsusb.htm
Object: FileSystem Object
Method: Get Special Folder"
This thumb drive contains precious vacation pictures so if anybody can suggest a solution, I would be really grateful - thanks heaps in advance!!
