Microsoft is to disable Windows Messenger and will activate Internet Connection Firewall (ICF) by default on XP boxes, in a move to better shield Windows PCs against hostile attack. Windows Messenger, a function used to exchange data between computers unrelated to MSN Messenger, has become more trouble than its worth in recent months since spammers latched onto the service as a way of launching pop-up spam boxes on targeted PCs. The service was also subject to a security flaw this month which created a mechanism for crackers to commandeer vulnerable Windows boxes. Microsoft has issued a patch but even so, the problem is another black mark against a not terribly useful service.
