Hello, Lately, I have been having trouble updating NOD32. As an example, my definitions currently read Feb 3. And of course, there are later definitions than that. I have had this problem twice (reinstall fixed it the first time) and noticed a pattern. NOD always seems to stop updating on a Friday, which happens to be the day that clean the registry, MRU, file system, etc. If I try a manual update, NOD acts like it is contacting the upgrade server. But, it never updates. I suspect the problem might be something that System Mechanic 6 is doing as I never noticed the problem before upgrading to that version. My question is, what file or registry key could possibly be involved here?
