Snow Leopard antivirus
The upcoming Snow Leopard update reportedly contains new anti-malware functionality, according to the Mac security company Intego. A number of beta testers have noticed a new warning screen that alerts users to malicious code. A leaked screenshot shows an alert dialog for an RSPlug Trojan contained in a disk image downloaded through Safari.
It is unclear if the OS X antivirus components scan just the downloads or full range of content on the system. Safari shows a similar warning dialog, although it provides a general warning instead of a specific reference to a particular threat.
Apple's Get a Mac ads have criticized the Windows platform as more prone to viruses or spyware. A number of security analysts have suggested Mac OS X continues to face more threats as the operating system grows in popularity and becomes a higher-priority target for hackers.
