in 2009, 34 percent of trojans were reported from north America (nAM) region, 30 percent from EMEA, 28 percent from ApJ, and 8 percent from Latin America (LAM) (table 14). Although the number of trojans reported from nAM and EMEA appears to have dropped slightly, this is mainly attributable to the proportional increase in trojans reported from ApJ and LAM, indicating that a similar amount of trojan activity was reported in both nAM and EMEA in 2009. Although the 2009 percentages are similar to 2008 percentages, it should be noted that the volume of infection counts for all regions approximately doubled in 2009.

trojan infection counts in the ApJ region continued to gain on EMEA in 2009 and were close enough that ApJ could potentially overtake EMEA in 2010. Even though both the proportionate increase and absolute counts for LAM were comparatively small, infection counts in that region increased the most, more than doubling in 2009.
the EMEA region reported 39 percent of the potential worm infections 2009, followed by ApJ with 37 percent, LAM with 14 percent, and nAM with 10 percent (table 15). EMEA overtook ApJ as the leader in worm infections in 2009, although the numbers are close enough that it may not suggest a significant shift in the threat landscape. the drop in ApJ and nAM is only due to the larger proportionate increases in EMEA and LAM. All regions have approximately doubled in infection counts, but the infection count in LAM increased the most, increasing by 187 percent, followed by EMEA increasing by 150 percent.
