Anti Flashback Trojan for Mac2.1.1

The operation couldn't be completed. (OSStatus error -67049)

Downloaded the new version. Tried to open it, but it gave me twice an error message ...

I can't glean from the description or from the publisher's website whether this thing will actually remove the malware, or only check for it.

This app is viable if for no other reason than it works on OS X 10.5. Apple has stopped supporting OS versions before Snow Leopard so there's no Java update for Leopard users. They might appreciate a tool that can check their systems for infection. Indeed, so might Tiger users. That said, they would all be well advised in the now riskier climate for Mac security to install an app like ClamXav that still supports older Macs.

I was using Dreamweaver on my Mac about 2 weeks ago. A very suspicious window closely resembling but not exactly like the flash installer popped up and said I was running an old version of flash and needed to update it. It directed me to enter my password, not giving me a choice. I refused. I restarted and no more installer. My flash version was not only up-to-date. It was a an advanced beta version. This has not happened since. I'd steer clear of scripts offering to delete this 'virus' since Mac has put out a very effective Java fix, and since this bug is supposedly very hard to remove. I would NOT click "update" on any flash installer that appears out of nowhere ordering you to install a version not listed on Adobe's web site. If it's not on Adobe's download page, it's fake.

I have serious doubts about the credibility of the people claiming this trojan infected 600,000 Mac computers. I think the numbers are a outright lie and exaggerated to scare people into buying AV software. I was not infected, none of my friends or family were infected. And none of the 10,000+ worldwide clients the company I work for had a single reported infection.

You may also try the Kaspersky Flashfake Trojan removal tool : info: http://www.securelist.com/en/blog/208193454/Flashfake_Removal_Tool_and_online_checking_site Download: http://support.kaspersky.com/downloads/utils/flashfake_removal_tool.zip :)

Be cautious of relying on scripts like this one. It is based on instructions for a specific variant from F-Secure, which do not work for all variants. It would be better to rely on some good anti-virus software, like Sophos Anti-Virus for Mac Home Edition or ClamXav, both of which are completely free, with no subscriptions or time limitations. And no, I'm not associated with either product.

All references to the F-Secure document for cleaning this malware are out-of-date. The correct one for removing the current variant that has supposedly infected over 600,000 Macs is http://www.f-secure.com/v-descs/trojan-downloader_osx_flashback_k.shtml which has been out for over a week now.

This may not be the most sophisticated software, but the developer has responded quickly and provided it for free (so far there's nothing else on MacUpdate - their review process is somewhat quirky.) I checked the script and it's not a trojan installer as one user suggested. See for yourself: -- -- Anti Flashback-Trojan -- -- Created by Moritz Wette on 06.04.12. -- Copyright 2012 Moritz Wette.

If you are concerned about the Flashback Trojan and want to check out, and, if necessary, fix your Mac using only Terminal, first go to this page (linked by the Ars Technica site): http://www.f-secure.com/weblog/archives/00002336.html, and then this followup page: http://www.f-secure.com/v-descs/trojan-downloader_osx_flashback_i.shtml That way you can avoid any anxiety about using this or similar items of software.

Just a comment: the info about the supposed 600'000 infected Macs comes from only 1 source, some called "Dr Web", a russian hacker or troll. All this is a scam ..

See "Flashback Checker Script" available here: http://macstuff.beachdogs.org/blog/

There's an alternative at this page: http://macstuff.beachdogs.org/blog/ Look for this at the above page: Flashback Checker Script

This Applescript application is completely bogus. It's just a wrapper for some shell commands that don't make sense and that the "developer" obviously doesn't understand. Don't download.

This is fast and hopefully effective, thank you developer

My computer is clean!
