IPS - File identification and false positives

Options

Hi,

we move medical files (e.g.: dcm files - CT slices) between VLANs. In many cases, the operation is interrupted and the USG500 log shows that the IPS module has detected the following threats:
Microsoft Office BMP Header biClrUsed Integer Overflow
HP Data Protector CRS Multiple Stack Buffer-Overflows

The log does not show exactly which file had a problem (there are thousands of them).

I have two questions:
How can I find the suspicious file?
I think these are false positives, how can this be corrected?

Thanks!
