Two Newcomers Make Their Way Into BitDefender's April Top Five E-Threat Report

A Fake AV and a Trojan.Keygen Make Their Debut

BUCHAREST, ROMANIA--(Marketwire - May 3, 2010) - BitDefender®, an award-winning provider of innovative anti-malware security solutions, today announced April's Top Five E-Threats.

April is the third month in a row to see Trojan.AutorunInf.Gen as the top e-threat representing 13.21 percent of the total amount of the global malware. This reveals that removable devices are used on a large scale and their owners are not that aware -- still -- of the damage waiting for them in the tiny gadgets.

Win32.Worm.Downadup.Gen (Kido or Conficker) is to be found once again shadowing the top Trojan.AutorunInf.Gen with 5.77 percent. It is the result of a successful exploitation of a Microsoft® Windows® vulnerability and unfortunately people are hesitant to update their operating systems and antivirus solution which could easily get rid of this obstinate worm.

Ranking third is a newcomer -- Trojan.FakeAV.KUE -- with a percentage of 2.72 of the total amount of infections. It's not much of a surprise here, since this past week has been mostly about rogue AV. This detection covers JavaScript code that is used to trigger fake alerts on websites connected to the placement of rogue antivirus software. These scripts are hosted on malicious sites and innocent victim-pages that have been infected. 

Win32.Sality.OG is positioned fourth (2.72 percent) in April's malware chart, just like last month it's again the sole representative of the file infector software. Shielded by a polymorphic packer, the Sality family is extremely difficult to detect and annihilate. In addition to that, the rootkit component of the virus tries to disable various antivirus applications installed on the infected system.

The second newcomer of the month is Trojan.Keygen.AX -- coming in fifth for April, which intercepts and blocks threats related to cracks, patches and keygens. Generating keys and patches for various applications is a common practice for commercial software on the Internet, P2P platforms, and instant messenger, download sites, and social networking environments. It may be popular, but it is also illegal and risky. So, play fair and safe!

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

1 Trojan.AutorunINF.Gen 13.21
2 Win32.Worm.Downadup.Gen 5.77
3 Trojan.FakeAV.KUE 2.72
4 Win32.Sality.OG 2.72
5 Trojan.Keygen.AX 2.66
OTHERS   72.92
