Just blocking bluetooth can not make you safe. There are a lot of arias:

* new sis or sisx installation.
The major cause of infection of testing and installation of newest unknown publisher and cracked sis or sis or jar files.
As a precaution scan the sis files on pc using a good antivirus & then install them on your phone.
Keep in mind PC antivirus can not protect you
all in the case of sis or sisx file scaning. it may be possible that some anvirus have the capability to check those files but major antivirus do not have the capability to catch symbian plateforn viruses.
