Over 50% of infections detected in February were spyware and trojans

Spyware and Trojans were the malware responsible for most infections in February. As in January, spyware accounted for 33 percent of the infections detected by ActiveScan. Meanwhile, Trojans have increased two points in comparison to January, causing 25 percent of infections. Regarding new examples of malware, 60 percent of those detected in February were Trojans. This is 11 points up on January.

"The distribution of the new variants that appeared last month is very significant. This classification indicates where malware creators are heading. The high number of new Trojans confirms that cyber-crooks have exclusively financial aims,” explains Corrons.

After Trojans came bots and backdoor Trojans, followed by worms (8%), dialers (3%) and spyware (1%).

Regarding February’s most active malicious codes, Sdbot.ftp is in the first position once again. Sdbot.ftp is the generic script detection that certain worms exploit to download Sdbot onto a computer. This worm has been the most active malware for more than twelve months.
