I have 2 recent PCs running windows 7 and Norton 2011. Several weeks ago the action centre on one told me I had no antivirus protection, although Norton was (and still is) actually running fine. After being annoyed and nagged by the action centre for some time, I simply switched off the warning. As a result windows then decided to download Windows Security Essentials on my behalf and kept wanting me to install it in order to fix the problem. I assumed that whatever bug was preventing windows from seeing Norton could be sorted out by an update/fix. However, after googling it, from what I can gather it turns out (according to Norton) to be a known Windows flaw which has been around for some time. Perhaps I'm being cynical but could it be MS aren't much bothered about fixing it in order to get people to switch to their security?? Anyhow, has anyone else had this problem and found a solution other than giving in to MS or just ignoring the warnings/nags. I'd prefer to stick with Norton as I think it still has many advantages over WSE (as backed up by Independent Lab reviews). Don't really want to go through the whole Norton uninstall - reinstall thing if its only going to happen again.
