Hi! These days my antivirus Avast found the Trojan HTML:IFrame-BW[Trj] in the wp-includes/js/prototype.js?ver=1.6 file of my installation on http://www.italianwebdesign.it
I solved the problem overwriting the whole wp-includes folder with the one I downloaded (ver 2.8.4), but It seems someone wants to bug my site.
This is a dangerous vulnerability, can you help me? Have you received some other warning from other users?
Thanks in advance, best regards
