Symantec virus protection products unable to find (still) W32/Fibbit.OL!tr
I have tested SEP, Symantec Messaging Gateway and Symantec Mail Security for Exchange and none of them find above mentined trojan/virus. Compewtitive products do find it - for example fortigate find the virus on the fly while scanning all the network traffic. Very bad performance from Symantec. The virus was found alreade nearly week ago.
