I would like to apologize to readers who came to this site yesterday and saw a warning from Google stating that the site had been infected with malware. It seems that my webhost was hacked and our files altered. I'm not very happy with their solution to the problem (which has taken days and not really fixed the issue), but I have removed the offensive code by hand. Although I suspect that the warning will remain until Google reevaluates the site, I believe I have made the necessary repairs. If you discover otherwise, please comment or send me an email. And keep your antivirus up to date!
Update: Google's webmaster tools appear to be giving my sites a clean bill of health now, although the malware warnings may persist for a few days.
Update 2: One problem with trying to troubleshoot from this distance is that it's hard to identify problems. I'm getting a lot of 403 errors ("You do not have permission to access this site"), but it's difficult for me to tell whether this is because my host's servers are falling over as they try to remove traces of this hacking attack, because they have reset my file permissions, or because I am on a flaky connection in Jakarta. Is anyone else seeing this?
I see no signs of malware on this page at the moment and there were no problems with the server (other than the usual MoveableType sluggishness).
