The malware is GONE, folks.
People are getting the warning from Google and Firefox because they (Google & FF) haven't updated their scans yet.
I've been working on my Auctiva listings most of the day without problem. Don't know whether I happen to be on a good server or what, but other than some slowness which has improved throughout the day, I haven't had any problems.
If you want to work on your listings there's nothing to stop you now.
