I want to know how to delay avast from checking for updates on start up. I know the default is 30 sec, but I want to delay even more to 120. Can anyone provide me the right steps? Thank you 
You could use the forum search function for ‘delay auto update’ many, many posts on this.
Here is just one, http://forum.avast.com/index.php?topic=114723.msg893240#msg893240.
Thx
You’re welcome.
