Bloodhound.Exploit.49 trojan found in MIMEBase.pyc

[Alex Hunsley]

Symantec antivirus has apparently picked up a virus in my Python 2.4 
(under cygwin):

Scan type:  Scheduled Scan
Event:  Threat Found!
Threat: Bloodhound.Exploit.49
File:  C:\cygwin\lib\python2.4\email\MIMEBase.pyc
Location:  Quarantine
Action taken:  Quarantine succeeded


There's info to be found on various pages, but it's a pretty terse 
explanation:
http://secunia.com/virus_information/22534/bloodhound.exploit.49/

Has anyone had this also? Is it perhaps a false positive?
