Virus definition file not updating
Any time you change a global settings it is effective for all security content download tasks from that point on.
For: F-Secure Anti-Virus Client Security, F-Secure Anti-Virus for Workstations, F-Secure Protection Service for Business (PSB) Workstation Security, F-Secure Anti-Virus 20xx, F-Secure Internet Security 20xx Open the Anti-Virus user interface by double clicking the "F" icon on Windows task bar.
Use Download updates (Security Configurations Download Updates) to specify where definition files are copied.
To import the file into the Avira program, go to the Update menu -Bitdefender Weekly Updates Bitdefender updates its offline definition files once a week on a Friday so they could be a nearly week out of date depending what day you download them.
While it might be fine for most users, letting your antivirus package update itself every few minutes isn’t great if you have a very small limit on your internet connection or it’s not very fast and constant updates are eating up your bandwidth, such as when using a mobile dongle on your laptop for example.
It’s also true that if you disable the updates or have computers that are constantly offline and not connected to the internet for long periods or at all, the virus definitions will get badly outdated in no time and your computer becomes more vulnerable.
Task-specific settings and global settings Note that only the definition types, languages, and definition and patch download settings are saved and associated with a specific task when you create it. However, all of the settings on the other pages of the Download updates dialog box are global, meaning they apply to all subsequent security content download tasks.
Global settings include: patch download location, proxy server, spyware autofix, security alerts, and antivirus.
The virus signature database is updated several times a day in order to ensure you have all of the latest known virus definitions so that you can protect your managed devices from these rapidly evolving threats.
