During the past month continued the rise of infections caused by worms, which accounted for more than 17% of the total. The creation of worms to steal confidential data capacity appears to be behind this increase, according to PandaLabs.
Trojans accounted for 23.70% of infections recorded in February by ActiveScan, Panda Security's online scanner. However, infections caused by this type of malicious code appear to have stalled in recent months, after not to let to grow for most of 2007.
Instead, the worms have increased for the second consecutive month, rising from 15% to 17.60%. The adware, which accounted for 20.71% of infections recorded in February, is stable.
"The worm boom is caused by an increase in their capabilities. Until now, most of these malicious codes were designed only to spread from one computer to another. In recent months, however, we observed an increase in copies of worms that have capacities of data theft, which hitherto were almost exclusively of trojans and spyware. It is a hybrid process that makes it increasingly difficult to classify a type of malware as belonging to one category or another, "says Luis Corrons, technical director of PandaLabs.
regard to the most active malicious code during the month of February, the list is topped by the Trojan Downloader.MDW. It is designed to download other malware on the infected computer. The worm Bagle.RC
ranks second, while the Lineage.GXD worm also designed to affect users of the online game Lineage, took the third position.
"As you can see, the majority of the most active of the month have been worms, which is consistent with the overall increase in infections caused by this type of malware that is becoming increasingly important," said Luis Corrons .
