In a recent study security vendor Trusteer found 10,000 PCs are infected with a trojan that goes by the name of Zeus or Zbot. In of itself this wouldn’t seem like all that much of a news flash to anyone but when you consider that the majority of those machines had an installed, and up to date, antivirus program.

Of that 10,000 31% of the machines didn’t have an antivirus program installed while 51% had current antivirus software installed.

The study was based on reports gathered from consumer PCs running Trusteer’s Rapport, which the company said detects Zeus through a unique fingerprint the Trojan leaves when it penetrates the browser process. Rapport is a browser plug-in that protects online credentials and transactions. According to Trusteer, the technology detects whether a PC has antivirus and whether it’s updated through the Windows Security Center.

Trusteer claims that its test of how effective antivirus is against Zeus in the wild is more accurate than most other antivirus efficiency tests, which it says are performed in the lab. The test result, the company said, is “disturbing and reveals that the vast majority of Zeus infections go unnoticed by antivirus products.”
