I keep getting trojans in omni.jar file whenever I try to install latest Firefox.

more options

After downloading the latest version (5.0) my antivirus alerted me that the omni.jar file inside Firefox install folder had been infected with a trojan. I have disinfected my HD numerous times between every re-install of Firefox, and it's always the same thing. The trojan doesn't appear anywhere else unless I ignore it and it starts infecting other files. My question, is this perhaps because of the installer being infected? Appreciate if you would look into this matter.

The trojan is TrojWare.JS.TrojanDownloader .Agent.~EWH@226922441 and it appears inside omni.jar, under

  chrome/toolkit/content/global/cpow/child.html   and
  chrome/toolkit/content/global/plugins.html

I use Comodo Antivirus I can provide a screenshot of the scan resault window.

Thank You.

This might be a false positive. There have been some discussions about that detection on the Comodo forums. I can't read all the posts, but maybe you have time?

False Virus confirm this please?
