November 13, 2011, Saturday – The world will once again witness two of world boxing’s greatest fighters trading punches in the ring to see who’s the toughest and who will be win the WBC Super Welterweight World Title. For those of you who are not boxing aficionados, more info about Pacquiao (winner of 8 major world titles and named as the Fighter of the Decade for years 2000-2009 by the Boxing Writers Association of America) is available here 

Peddlers of Fake AV once again see this as a good opportunity to infect computers over the internet via Search Engine Optimization (SEO) poisoning attacks. The infection delivers fake system alerts designed to fool users into buying fake antivirus products (providing a neat source of income to Fake AV gangs).

Clicking any button will still take users to fake scanning pages – a common method used by fake antivirus to force users to download and execute various malicious files. Fake scan results are shown below:
