Trojans jump to 70 percent of new malware in second quarter of 2009

Trojans accounted for 70 percent of all new malware detected between April and June 2009, according to data compiled in the latest Quarterly Report from PandaLabs.

One of the most notable findings of the report is the 6.25% drop in spyware, which now represents just 6.9% of all new malware. In contrast, adware rose dramatically over this period, from 7.54 percent in the previous quarter to 16.37 percent. This is largely due to the increase in fake antivirus applications, a type of adware that passes itself off as a legitimate security solution. As for worms, their percentage has also risen slightly, now accounting for 4.4 percent of all malware.

Trojans were also responsible for more infections than any other type of malware over this period. This type of malware was behind 34.37 percent of all infections detected by PandaLabs, an increase of 2.86 percent with respect to the previous quarter. Adware infection levels remained stable, accounting for 19.62 percent of the total. Worms increased slightly (0.89%), staying in the picture due largely to the effectiveness with which they spread.

When broken down geographically, Taiwan continues to top the list with 33.63 percent of computers infected with active malware. Turkey and Poland come next, with just under 30 percent. Three Scandinavian countries, Sweden (14.2%), Norway (12.48%) and Finland (12.17%), are the countries with the lowest number of computers infected by active malware during the first half of 2009.
