After noticing a red 'X' showing on my N360 icon, I viewed the status screen. It said that the virus definitions were not complete, and that the last update was 14 days ago (now 17 days). I clicked the 'Fix Now' button and virus definition download started. After 8 hours of run time ( laptop on dial up connection) the status screen was showing that ~80 megs of ~114 megs had been downloaded. At that point, download terminated and the installation phase started. After completing it terminated with the message "Status: Failed to complete all updates" . The details showed that it had "processed 7 out of 8 updates".
I had the same problem back at the end of July. I tried running the definition download manually several times with the same result. At that time, I uninstalled N360, then downloaded and installed the latest version. It seemed to work OK until 17 days ago. When I had the problem back in July, it managed to fill up all the available space on my hard drive with virus definition records. Many of them had file type of .tmp. At least it didn't do that this time.
After running successfully for several years, why am I suddenly having having this problem, and what can I do to fix it?. I read several items on this forum from people who had the same or similar problem, but it didn't really help me to a solution. Most of them were able to get manual update to complete successfully after one or two attempts. That doesn't seem to work for me. Also 114 megs seems too large, and 8-12 hours of run time seems kind of excessive, even with a dial up connection. I would appreciate any help with this that anyone has to offer. I hope uninstalling and redownloading N360 isn't the only answer. That's a real pain with dial up!
