As per the list, the number one position is taken by Trojan.Clicker.CM, which has become very effective by defeating popup blockers. Consequently, it now represents almost 11% of infections detected by BitDefender labs in July 2009.

Another Trojan, AutorunINF.Gen is at number two whereas Trojan.Wimad is at number three, slightly rising to just over 6% of infections. Downadup.Gen, also known as Conficker or Kido is at fourth place. It increased over 4% of infections and moved up one position on the top ten list.

A rootkit-installing file infector, Win32.Sality.OG, jumped from number six to number five on the list for July 2009.

An old SWF, Exploit.SWF.Gen occupies the sixth place on the list. Its fame is partially because of the fact that Adobe was distributing an old edition of the player through its site until recently, depending on the player's auto-update function (an optional function) to pull-in the required security patches.

Trojan.Autorun.AET is at seventh place, which is another Trojan exploiting the Autorun vulnerability in Windows. Trojan.JS.PYV is at number eighth position with 1.91% of total infections.

Exploit.PDF-JS.Gen is at ninth position, an exploit that uses vulnerability in the manner some versions of the Adobe PDF Reader parse embedded JavaScript.

Finally, Worm.Autorun.VHG is the latest threat on BitDefender's Top Ten E-Threats for July 2009 and acquires the tenth place. Worm.Autorun.VHG is a worm that exploits the Autorun bug in Windows, which made the Conficker/Downadup worm popular.

In the light of these sophisticated and malicious Trojans, security experts advise users to be careful and use updated antivirus software and firewall to evade falling to these threats.
