I agree, iOS is terrible on a Desktop Computer, & now Windows & every flavor of Linux is going that way.
I also like how the communities no longer support this version.
Huh, I'm here everyday trying to help!???
ClamXAV, free Virus scanner...
Little Snitch, stops/alerts outgoing stuff...
Flashback - Detect and remove the uprising Mac OS X Trojan...
In order to avoid detection, the installer will first look for the presence of some antivirus tools and other utilities that might be present on a power user's system, which according to F-Secure include the following:
If these tools are found, then the malware deletes itself in an attempt to prevent detection by those who have the means and capability to do so. Many malware programs use this behavior, as was seen in others such as the Tsunami malware bot.
The most current flashback removal instructions are F-Secure's Trojan-Downloader:OSX/Flashback.K.
disable java plugin and use a modern browser instead of Safari ( 5.0.x on Leo is outdated ) is the only way to stay safe from the current trojans. They all depend on Java in the Browser.
Apple does obviously no longer support Leopard, so you are on your own.
Alternatively if you dont plan for new Mac OS or new Apple Computers but still want a modern and supported OS which will run on Macs you could install a Linux of your choice ( available for PowerPCs and Intel-Macs ), they usually ship with the latest Firefox that supports Java and Flash. But this makes it not any dot "safer" : Java as well as flash is platform-independant code, so malware can easily hit these systems also sooner or later.
