I have been using NOD32 AV 3.0.621 with Outpost V6 & was so impressed with NOD (having come from KAV!) that i went & tried ESS 3.0.621 with a totally restored factory shipped software on my hewlett Packard laptop. I did all the full Vista updates & then installed ESS and then when i rebooted i got the BSOD but because Vista asked me if i wanted to get solutions to the BSOD I clicked yes & it immediately restored my laptop to the point of Pre-installation of ESS so I never got the dump file or error? Has anyone else experienced this BSOD with ESS? No problems with the AntiVirus version all is working really well?
