Trojan.Clicker.CM Vanishes From BitDefender's February Top Five E-Threat Report

Removable Devices Are This Month's Main Vectors of Infection

BUCHAREST, ROMANIA--(Marketwire - March 1, 2010) - BitDefender®, an award-winning provider of innovative anti-malware security solutions, today announced February's Top Five E-Threats. Last month's number one e-threat, Trojan.Clicker.CM, totally disappeared from the current landscape. Instead, a generic mechanism to spread malware using removable devices, such as flash drives, memory cards or external hard-disks -- Trojan.AutorunInf.Gen -- is the top e-threat of the month, with 9.09 percent of the total amount of global infections.

"External devices should be scanned on a regular basis," advised Catalin Cosoi, BitDefender's senior researcher. "This safe practice should be used especially when these devices have been plugged in library computers, copy shops and other public locations that are known to be sources of infection."

Win32.Worm.Downadup.Gen is up one place since January. Ranking second, with 6.24 percent, this worm exploits a well-known Microsoft® Windows® vulnerability.

"The continuous presence of Win32.Worm.Downadup.Gen -- also known as Conficker or Kido -- in our monthly e-threat lists proves most users are reluctant to update their operating system and locally-installed antimalware solution, in addition to installing the security fixes issued by Microsoft® more than a year ago," explains Cosoi. "Newer variants of the worm also install rogue antivirus applications, amongst others."

BitDefender's third and fourth e-threats for February are Exploit.PDF-JS.Gen, with 5.13 percent, and Exploit.PDF-Payload.Gen, with 4.21 percent of the total amount of infections. These generic detections deal with manipulated PDF files exploiting different vulnerabilities found in Adobe® PDF Reader's® Javascript engine. Their purpose is to execute malicious code on the compromised computers.

Torrents continue to be one of the favorite vectors of malware distribution. With a percentage of 3.37, Trojan.Wimad.Gen.1 remains the number five e-threat for February. A not yet aired episode of your favorite series or a box-office title could be the perfect cover for this Trojan.

BitDefender's February 2010 Top Five E-Threat list includes:

1        Trojan.AutorunINF.Gen       9.09

2        Win32.Worm.Downadup.Gen     6.24

3        Exploit.PDF-JS.Gen          5.13

4        Exploit.PDF-Payload.Gen     4.21

5        Trojan.Wimad.Gen.1          3.37

OTHERS                              71.96
