With no other options at present I
thought it might be of some help to
run the various Avast scans to see if
they turn up anything ?

I prefer to update manually from the
source like you suggested.

The way I find the 'source' is to go
into Programs and Features and find
the program and highlight it. It
usually has some sort of link with
'support', 'updates' etc. However, If
I'm doing it wrong or there's a better
way I would appreciate it if you would
point me in the right direction.
