How regular are signature updates usually? Daily mostly I hope? Or do none appear at weekends?

Here is describe what the VPS version number means: http://forum.avast.com/index.php?topic=3878.0
It’s only updated when needed, there is no placebo updates, even less dialy, if it’s not necessary.
Generally, three or four times a week. Sometimes, it could be three at a day 
Thanks for the links. It is what I suspected, no weekend updates, just on weekdays. Handy to know.
No, it’s not true… Can be and in fact there were a lot of weekends updates when needed (new virus in the wild, etc.).
Ah okay, haha. I didn’t look back far enough
