A report says that Asia and Latin America's Computer networks are the most hit by a fast-spreading computer virus.

A computer worm or virus, called Conficker or Downadup, the most severe outbreak in years, continues to spread after infecting millions of corporate computers and servers machines by some estimates was first appeared in middle October or first week of November has recently become more prevalent.

According to Symantec analysis, the top 3 in Asia are China, Taiwan, India and the top 3 in Latin America are Brazil, Argentina, Chile are the countries that have been hit hardest by the virus, which started spreading about two months ago but is thought to have infected over 9 million over the past few weeks.

China gets on top, almost 29 percent of the infections where tracked by Symantec, Symantec's vice president for Security Response Alfred Huger says We're not seeing anywhere near the number of infections in Western Europe and North America.

Commenting about the infections, Huger looks at pirated software, I think that piracy plays a role, though I don't know if it's the key contributor, Huger said.

Security experts said they are worried about the next step in the attack. All indications, though, seem to point to this being a real threat, though a Microsoft patch has been available since October.
