Virus and Application updates

How often does Virus Protection and Applications update?  Is it daily or when threats are discovered?

Hi Alex,

We're glad to clarify this for you.
AVG is set to update virus definitions every 4 hours automatically to protect your computer against emerging threats.
The program update might be available if our developers release a new version. 
However, you can manage the virus definition update & application update depending on your preference, as mentioned in this article
