Hi, Any assistance is appreciated. Running version: 188.8.131.52 Business Edition (no firewall). OS: Windows 7 32-bit Since we installed NOD32 all 10 of our systems are locking up. This occurs when using a program based on javaws.exe which loads off a local server. When the computer locks, it is completely unresponsive (cannot ctrl + alt + del) and must be forcefully restarted. I have: - Disabled NOD32 - Added exception for javaws.exe When NOD32 is un-installed, the issue doesn't occur. NOD32 is installed on a Windows 2003 terminal server as well, running the same javaws.exe application - but doesn't have these errors. It is only the Windows 7 workstations which are locking. Is there any thing else we can do?
