Hi DubbleD, It is not unusual for an anti-virus to update more than once a day. As long as you are having no other internet connection problems, aside from Symantec's Live Updates, I don't see how your problem can be attributed to Dell drivers. As ky331 mentioned:   If I were you, I would uninstall Live Update, followed by uninstalling Norton, and running the removal tool per instructions. After the reboot, I would install Microsoft Security Essentials. I've been using it for several years on multiple computers running Windows 7 Pro 64-bit.. If you don't have Malwarebytes Anti-Malware installed, that would also be good to add. The Pro version runs well alongside MSE, and has the option for auto updating and realtime protection. If you prefer the free version, that can be updated manually and run manually. Good luck. Let us know if you have any additional questions.
I have been having major problems with my Security Software, Norton Antivirus, over the past 2 months.  Norton discussion forum members are reporting that my case is isolated, and to check with Dell for assistance. I have posted a discussion topic on the Symantec website detailing the specific problem I am experiencing... [URL] Here is how my Norton Avtivirus (NAV) has been malfunctioning since early November: Norton Avtivirus (NAV) Automatic Live Update routinely fails to successfully install Virus Definition X64 Incremental Updates (generally under 1MB in size), following the awakening of the PC from hibernation/sleep periods, and when booting up the PC from a full shutdown.  I will then run Manual Live Update immediately after the failed Virus Definition X64 Updates, and Manual Live Update downloads/installs a 160MB full Virus Definition X64 file!     NAV occasionally needs to update the very large full Virus Definition X64 file, perhaps once every month or 2, but not 2 times/day for me sometimes, and 20+ times/month for me since November. Symantec forum members suggested I check with Dell for the latest drivers, to which I've noticed that  Dell does have new BIOS (Release Date 10/15/2013), which I have not yet installed. My Norton Antivirus Version 21.1.0.18 (which is the latest version, just released in October) should work using the original BIOS, shouldn't it? Other than this 2-month long problem with my NAV, the 2013 Dell Inspiron 17R 5720 purchased last January has worked well with no other issues/problems to speak of. What is confusing to me is how/why my NAV worked perfectly from January-November with the original BIOS, and now it is malfunctioning badly.   So, my question is, will updating my PC with the latest BIOS (Release Date 10/15/2013), address this ongoing Norton Antivirus malfunctioning?? Or is there another driver update which might address this problem? Any help is much appreciated. DD 2013 Dell Inspiron 17R 5720  Windows 7 64 Bit SP1 Norton Antivirus Version 21.1.0.18
