Re: Blue screen errors I have had a bsod bad_pool_caller two days ago if i reboot the pc after installing Nod32 v3 over v2.70. Since I tried V3 not the first time I noticed that before I got the bsod the icon of V3 was not in the task-list near the clock after installing. The other times were after the installation before rebooting the pc without bsod both icons (v2.7 and V3) in the task-list. After this I got my image with v2.7 back, installed v3, got two icons before rebooting and no bsod. So I think there must be a problem with the installation of v3. But as I wrote only one time. I dont remember a bsod before on my machine, xp sp3. sorry, this is not for ESS, this is for Eset nod32.
