Not meaning to hijack this thread
But
What Firewall?
using zone alarm
On my system which also was previously AVG
after clicking manual update
OR
after a day or so when auto update should have run
update will run
if I turn Firewall off for a brief period of time
or
If I reboot
I may watch this thread to see how you solve this one
you think

about the only things I have left to do is run the Norton, Panda, and other removal tools- McAfee
This system has had em all at one time or another
This may have been asked already but in addition to AVG did your system come pre-installed with any AV?
