[Boost-users] Boost and Norton 360

Hi, I have just installed boost 1.53 32bit using the Sourceforge Visual Studio installer and my security software (Norton 360) has quarantined three files as being high risk: *boost_math_tr1f-vc110-mt-1_53.dll *boost_thread-vc110-mt-gd-1_53.dll *boost_filesystem-vc110-mt-gd-1_53.dll Does anyone know if this is common? Can I safely restore these files? Thanks, Scott
