I just tried NetVeda SafetyNet 3.61 (downloaded today) on Windows 2000 sp4. After reboot and logon, it displayed a configuration screen. After setting some options, I launched Opera 8.5. I got some alerts regarding DNS and web access to which I selected "always allow". Then, boom! BSOD variety which I've never ever seen before: a device driver has corrupted the executive memory pool. I'm trying Fileseclab next but am a bit concerned about reports of constant cpu usage I've seen in these forums.
