Thanks DavidR . I did see your post and I should have explained more thoroughly.
I've just got another prompt popping up telling me, "An update to your version of avast is now available..."
"a new version of the program (2015.10.2.2213) is available."
I click to upgrade, steps 1 & 2, "updating statistics" and then"Already up to date. 2015.10.2.2209 - there is no such version.
I guess I'm doubly annoyed because the "cloud" product has a similar glitch. (2015.10.0.2504 vs 2015.10.1.2504)
