BAD_POOL_HEADER BSOD from Firefox portable 27.0.1 from removable drive

[Thenin]

Whenever I launch Firefox Portable v27.0.1 (from PortableApps.com) from a removable SATA-III drive, I get a BSOD with description "BAD_POOL_HEADER", with Bug Check Code = 0x00000019.

This is a week-old Windows 7 Pro 64-bit SP1 installation, with all the most recent Windows Updates, on my new home-built desktop. (See system specs)

Everything runs fine from the main system disk, but Firefox Portable on the removable drive fails. The few other apps I've tried on the removable drive seem to work fine, but I haven't tried very many.

I've run Raxco's PerfectUpdater to check and update all drivers, and now it says there are no newer drivers.

BlueScreenView points to avgntflt.sys, which is part of my Avira AntiVirus suite, but the last time it blamed a USB driver, so it kinda looks like the culprit isn't always the same.

The requested info archive has been uploaded, and is attached. Thanks for your assistance.

The BSOD is caused by Avira.

Description here: Driver Reference Table - avgntflt.sys

Uninstall Avira. At least as a test. Use Microsoft Security Essentials as your antivirus with windows inbuilt firewall, and free MBAM as the on demand scanner.

Download, install and update those, and then run full system scans with both of them, one by one; for a security reason, as the installed antivirus failed.

Let us know the result.
