Il giorno 21 aprile 2010, per una limitata finestra temporale, McAfee ha rilasciato un aggiornamento che causa la perdita della connessione di rete sui computer XP Service Pack 3 attaccando erroneamente
svchost.exe (falso positivo). Sono riportati anche errori più gravi come BSOD e riavvi.
McAfee’s “DAT” file version 5958 is causing widespread problems with Windows XP SP3. The affected systems will enter a reboot loop and loose all network access. We have individual reports of other versions of Windows being affected as well. However, only particular configurations of these versions appear affected. The bad DAT file may infect individual workstations as well as workstations connected to a domain. The use of “ePolicyOrchestrator”, which is used to update virus definitions across a network, appears to have lead to a faster spread of the bad DAT file. The ePolicyOrchestrator is used to update “DAT” files throughout enterprises. It can not be used to undo this bad signature because affected system will lose network connectivity(*).
