Trojans rule July's top ten e-threats

Trojans continue to dominate the latest BitDefencer labs’ e-threats list, making this the most common malware for the second month in a row.

Number one spot on the list goes to Trojan.Clicker.CM, which is becoming increasingly effective by bypassing popup blockers. As a result, it now represents over 11 per cent of infections discovered by online security BitDefender firm’s labs in the past month. Another Trojan - AutorunINF.Gen - holds its ranking at number two, while Trojan.Wimad continues to hold the number three slot, slightly increasing to just over 6 per cent of all infections monitored.

In fourth place is Downadup.Gen, also known as Conficker or Kido. Downadup.Gen increased to over 4 per cent of infections, and gained one position on the top ten list. Win32.Sality.OG, a rootkit-installing file infector, climbed from number six to number five on the July list.

An old SWF, Exploit.SWF.Gen, is still in heavy use in the wild, and so occupies sixth place on the July list. Bitdefender says that its popularity is due partly to the fact that, until recently, Adobe was distributing an old version of the player via its website, relying on the player's auto-update feature (which is optional) to pull-in the required security patches.

Seventh position belongs to Trojan.Autorun.AET, which is another trojan exploiting the Autorun vulnerability in Windows. Trojan.JS.PYV comes in at number eight this month with 1.91 per cent of total infections. Gaining popularity in ninth position is Exploit.PDF-JS.Gen, an exploit that uses a vulnerability in the way some versions of the Adobe PDF Reader parse embedded javascript.

The latest emerging e-threat to be detected by BitDefender labs is the Worm.Autorun.VHG - a worm that exploits the Autorun bug in Windows, which has made the Conficker/Downadup malware famous. The Worm.Autorun.VHG comes in at number ten on BitDefender’s list of top e-threats for July.

  1. Trojan.Clicker.CM - 11.41 per cent
