BSOD every night

One minidump usually isn't enough,but I've seen the same problem recently and it was fixed by removing the program.The culprit is vsdatant.sys,which is a Zonealarm file.
 
ah I see thanks for the help.

i got some other dump too but they all have same properties just different dates.

I think I will uninstall The zone alarm and install newer version. If the .sys file is still there after the uninstall should I remove it manually?
