Next in the ranking, although a long way behind with 14.41%, comes the United States, followed by Mexico (9.37%) and Brazil (4.81%). Those countries least infected include Peru, the Netherlands and Sweden, all with ratios under 1%.
According to Luis Corrons, Technical Director of PandaLabs: “Along with rogueware, botnets and zombie computers have increased by more than 30% so far this year. This is the simplest way for a hacker to take control of computers to distribute spam or malware, therefore making it more difficult to trace and detect the real culprit. The problem is that owners of these zombie computers will be committing crimes without realizing, and could face having services withdrawn by their ISPs or even prosecution.”
