Dr Solomon's Software, the current publisher of the Virex anti-virus utility, announced two Virex updates in quick succession last week to find and remove two newly discovered variants of the AutoStart 9805 worm, originally reported in "Autostart Worm Breaks Mac Malware Silence" in TidBITS 428. Dr Solomon's says the variants use different filenames from those used by the original AutoStart 9805 worm, making them harder to find, and replacing previous versions of the worm, if found. AutoStart 9805-B doesn't restart the computer, as do the others, and AutoStart 9805-C doesn't directly damage files. Also, the B variant targets different kinds of data files than the original for its damaging sweeps.
Improve Apple Services with AirPort Base Stations
You can make iChat file transfers, iDisk, and Back to My Mac work better by turning on a setting with Apple AirPort base stations released starting in 2003. Launch AirPort Utility, select your base station, click Manual Setup, choose the Internet view, and click the NAT tab. Check the Enable NAT Port Mapping Protocol (NAT-PMP) box, and click Update. NAT-PMP lets your Mac OS X computer give Apple information to connect back into a network that's otherwise unreachable from the rest of the Internet. This speeds updates and makes connections work better for services run by Apple.
