Yikes! I happen to visit one of UMNO sub-page and when I returned to their front page, a big warning was shown indicating the UMNO website (umno-online.com) is infected with Malware. The Malware elements originated from www.bokehphotostudio.com
UMNO is the largest political party in Malaysia and with millions of members, their webmaster would be notified of this Malware infected really soon.
