SOLVED: Upgraded to Eset Nod32 BE 4.0.474 - computer hangs at login after reboot Hi I recently did an upgrade of Eset Nod32 BE 4.0.474 on a fully patched Windows Vista SP2 - 32 bit, Danish. This upgrade was done over an older Eset BE 4 (don't recall the exact version number, but fairly recent), keeping it's configuration. Installation seemed to go fine, but after reboot the computer started hanging at login - sometimes never leaving the login screen, sometimes showing some or all of the desktop. The mouse often stays responsive (if at desktop), but login never completes, no programs can be started, and computer doesn't respond to CTRL-ALT-DEL. I first tried rebooting into safe mode to disable the Eset service, but this didn't change anything. I then booted in to safe mode and used the official uninstall tool. After a new reboot computer was back to normal. I have since tried to install several times more (and to repair), and tried with the 4.2 Beta, result has every time been that Nod32 (and Windows) complains about Nod32 not being able to start right after installation, and that computer becomes unresponsive after reboot, with removal via safemode and uninstall tool as only option. I have scanned the disk (including bad sector scan), and is currently running a memtest that doesn't seem to find anything. I have also done a virus scan using Eset onlinescan and Bitdefenders onlinescan, finding nothing. And I have verified that no other AV products are currently installed. How do I proceed from here?
