I found that my antivirus was reporing malicious code trying to get executed everytime I visited this blog.

At the beginning, I thought the theme I’m using contained the nasty directives… but a quick investigation revealed that the problem was happening in other blogs too and the possible reason was a bug present in WordPress. Maybe they used a webbot to look for WordPress sites and try to exploit them automatically… This method of distribution could lead to a massive infection of malware and the users at risk would be those using obsolete versions of software, software with bad security (IE) and no protection at the OS-level like an antivirus/firewall.

I highly recommend you use Firefox and its great security plugins like NoScript, the latest versions, a good antivirus and to keep your OS patched and up to date.

I upgraded the blog to the latest version of WordPress and thightened security to prevent other intrusions.

I can asure you I won’t let this happen again!
