Trojans account for 70 per cent of all malware in second quarter of 2009
Trojans accounted for almost three quarters of all new malware between April and June this year.
According to the PandaLabs quarterly report on malware activity, there was a 6.25 per cent drop in spyware, while adware rose from 7.54 per cent in the previous quarter to 16.37 per cent. The company claimed that this was largely due to the increase in rogue anti-virus applications.
However Trojans were responsible for more infections than any other type of malware over this period. This type of malware was behind 34.37 per cent of all infections detected by PandaLabs, an increase of 2.86 per cent with respect to the previous quarter.
In terms of specific strains of malware, the number one ranked specimen between April and June 2009 was Downloader.MDW, a Trojan designed to download other malware on to computers. The Virtumonde spyware and Rebooter.J Trojan were also among the malicious codes that caused most infections.
