For the last two days the anti-virus update fails with a download error, that's the message I get. Anti-Spyware updates fine, as do, Microsoft Security, High Priority and Software updates. Also have updated Adobe Reader, Java and three other applications that I have installed. Not having a better idea, I did a clean uninstall of Zonealarm Extreme Security and reinstalled. It didn't help, still get the AV update download error. Any ideas?
