Hi Guys, We have an ongoing issue with one of our users whereby they intermittently get the following error messages which can often be resolved by rebooting the machine: “Virus scanner initialization failed. Antivirus protection will not function properly.” What we’ve tried: * Manual uninstall and reinstall of NOD as per KB article. * Wiped the PC and re-installed all apps only to have to issue re-occur * Deleted and recreated the user’s Windows profile only to have the issue re-occur * Setup the user on a different workstation with a new installation of NOD only to have the issue re-occur again! This has us scratching our heads a lot and we can't understand how the issue could follow this user around to a new PC. Currently as it stands the PC will successfully update its definitions about half the time. When it does, it works for a while before erroring again a few hours later. Some details about the setup in question: O/S: Windows XP SP3 (for both PCs which were tried) NOD32 AV Client version: 4.2.64 NOD32 Server version: 4.0.138 The PCs are running in a Server 2003 AD environment without roaming profiles. I also want to mention that we've tried going through the official NOD32 support channels and simply aren't getting a response. We created a support case the official website only to get an automated response to try our local support in Australia. The only issue with that is we've sent multiple e-mails to firstname.lastname@example.org and have never gotten a response. It seems like nobody even reads that e-mail address? Hopefully you guys can help..
