BitDefender says that in September, the top three e-threats are a malware trifecta which it says should already be familiar to those following developments in the malware world - the Wimad Trojan, the Clicker Trojan and a generic detection for Autorun using Trojans. These three, says BitDefender, are once again the most prevalent threats, accounting for no less than 25 percent of all infections recorded during September.
BitDefender also says that Conficker, in its various guises, is detected by as Win32.Worm.Downadup.Gen and occupies the fourth spot, with a sizeable 5.5 percent of the total number of infected files detected during September.
A long-time veteran of BitDefender's top 10, Win32.Sality.OG, dropped from fifth to seventh place in September, with the encrypted, polymorphic file infector apparently set for a very long “cybercrime career".
The last three threats in BitDefender’s top 10 list include two threats using the Autorun security loophole in older versions of Windows, occupying the eighth and ninth positions, with one of them actually a downloader component used to spread the well-known Conficker or Kido worm (aka Downadup); and, in tenth spot is Trojan.Skintrim.HTML.A, a type of HTML page usually associated with adware programs such as Navipromo.
