There are 3 signatures for PDF, one for 0:53, one for 54:54, and one
for 55+. Each ClamAV version loads appropriate one.
Unfortunately due to a bug in 0.96.2 the 54:54 signature doesn't work
properly.

Should be fixed in bytecode.cvd version 41, it'll report malware
detected inside PDF as BC.PDF.Parser.MalwareFound.
In 0.96.3 the name will be fixed.

Please report if you encounter any other problems with it.

Best regards,
