After following these instructions I can use VirtualBox again without uninstalling Avira Antivirus.

Unfortunately, the issue that you are currently experiencing is indeed related to a new bug. We are currently working to solve this bug as soon as possible.
Meanwhile, the solution that I am proposing to you is to simply disable the avipbb driver.
In order to disable avipbb driver, the following procedure can be followed:
• Open Avira configuration and go to General -> Security.
• Disable product protection options (all three).
• Press Ok button to save configuration.
• Press Start->Settings-> Control Panel->System.
• Start "Device Manager" in the tab "Hardware".
• In "View" menu activate the option "Show hidden devices".
• Now select the node "Non-plug and play drivers".
• Right-click on the driver "avipbb" and select "Properties".
• In tab "Driver" select the option "Disabled" and click OK.
• Close all and reboot.
After these manipulations, it is possible that the Mail Protection and Web Protection services will cease to function. Just in case it`s happening, do not worry and rest assured that your computer's security is in no way being jeopardized; the Real-Time Protection will continue to protect you by scanning any files.

FWIW, I got bit by this today. I also use Avira Free Antivirus (if there's a better one I'd be glad to consider it).
In the end, I did all the above and VBox 5.0.10 seems to work now, at least for Ubuntu.
I'm not sure if disabling AV product protection is just to allow you to disable "avipbb" or not though -
out of an abundance of caution I re-enabled the Avira product protection checkboxes as they were before, and things still appear to work, even after reboot. That said, I'm not sure what avipbb actually protects so I feel this compromises security somewhat.
(Also, right click your Avira taskbar icon to select "Configure..." - if you just open the main Avira window it's a bit tougher to find the configuration area.)
Finally, here's the link back to the thread on Avira's support forum:

(I'm considered "new"... thus the ridiculously convoluted link above. Google it to be safe if you'd prefer.)
