I always do a custom install of Avast and I do install the software updater since it will remind me that something (software) needs to be updated if I didn't catch it. However, I always install it directly from the vendor's/manufacturer's site. For example, if Flash needs to be updated (it seems like it does every week!), I go directly to AdObe to install it rather than any other site. After I download something, I always scan it with MBAM first to make sure it is clean prior to installing it, and Avast is always running in the meantime. I don't take chances and so far have never gotten anything.

Only way to go. Use Software Updater as a
guide, and do the work yourself, as SafeSurf suggests.
So, if you get a pop-up from avast! such as the one you posted about (a pop-up here that is something that is related to Software Updater but shown as a
new feature of avast!), ignore it. Don't rely on any program to do the work for you, not even avast!. Just use the new information and research on the internet.
Use Google to find what you need to know.
Why this happened:
avast! is basically assuming all users do not follow SafeSurf's sage advice, and want avast! to do all of the necessary work for them. Not so.
