No problems by manuel updates. I have done this for the last couple off days.
No warnings. No errors.
Last manuel update is 625-2.
when I start my computer, Avast shows the red and green arrows, looking for updates, but then nothing happens.
At first I assumed that there where no updates, and surfed happily on the net.
Then at some point, I noticed on "Softpedia" that there was new signatures, and then I looked at my VPS file and noticed that I missed something.
I have no Firewall, except for XP´s one.
