I use The Bat! e-mail client on a Windows XP SP2 system. The messages.tbb file contains -- among hundreds of other e-mails -- an e-mail with the EICAR test virus as an attachment. When I scan the file with the NOD32 version 2.7 on-demand scanner, it finds no virus. However, when I save the individual e-mail as an .eml file on the desktop, the on-demand scanner is able to spot the test virus. It is as if NOD32 cannot scan inside the messages.tbb file. I have enabled scan archives, runtime packers, e-mail files and all other options in the NOD32 On-Demand (Manual) Scanner Control Center Profile. Incidentally, BitDefender anti-virus and others are able to spot the test virus inside the messages.tbb file. Can any other Bat! users confirm this problem? Any solutions?
