BSOD (tcpip.sys & Driver irq not less equal error)

Hi,
Can anyone help me out please?
I keep getting the BSOD...
Today in a space of 40 min happened probably 3 times.
It says something about tcpip.sys and Driver irq not less equal...
I've upload a couple of minidumps.
Thank you so much!

Uninstall Zonealarm and see if the crashes stop. Use the Windows firewall for the time being. Both crashes have vsdatant.sys listed.
