Firefox crashes without generating error report

Hi,

I am facing an unusual problem with Firefox 3.6.3. Previously when i tried opening firefox it gave an error mozcrt19.dll is not a valid windows image. I re-installed a fresh copy but the problem persisted. I again re-installed it in a different directory, the mozcrt19.dll error was gone but soon as firefox open, it crashes after 4-5 seconds, and the crash reporter comes up. I tried clicking on error report link but after clicking it, the crash reporter also disappears.

I am clueless about what to do next.

Please help me!!

Try to disable your anti-virus software to see if that helps. It may be monitoring Firefox too aggressively.
