I have the following problems with the 2 mentioned zonealarm software nvidia graphic drivers. both problems apply to zonealarm pro and free.

Using zonealarm and nvidia graphic driver 257.37, my computer was unable to enter standby. computer stayed on, but screen remain blank. have to restart to fix it. I uninstalled zonealarm and my computer was able to enter standby without problem.
using the newest nvidia graphic driver 258.96, i have frequent BSOD's, the cause being vsdatant.sys uninstalled zonealarm, no more BSOD's.

I tried reinstalling the graphic card drivers using a clean install, both problem persists. I use a laptop on use nvidia mobile drivers. can anyone help me with this problem? i really like the zonealarm software and wish to use it. thanks!
