I saw the reported problem almost immediately after upgrading - ZA has a warning that the antivirus/spyware defs aren't updated, and I have to update manually. I got the warnings both on my WinXP Pro SP3 desktop and my Vista Home Premium laptop. I did the recommended procedure, resetting restarting. Worked for a few weeks, now failing again. I've seen a reference to a newer version of 9.1.x - can someone give me the link? My so-called automatic update doesn't pick it up.
