Slashgear reports Apple is working on a removal tool for Flashback, a Mac virus that has reportedly infected over 600,000 Mac computers. Its unknown when the tool will be ready, but in the meantime there are some third-party tools and guides that will aid you in removing this virus.
At this point other than knowing Apple is working on its own direct malware removal tool, we don’t have a firm date for when the tool will be released. Apple did reveal yesterday that it was working on the tool to detect and remove Flashback. I would imagine once the tool is ready, it would be offered via Apple support website and via the integrated update software Mac OS X. I would bet on it being offered directly via the integrated update software on the Mac computers.
