Since the install of ZA Antivirus I will occasionally lose my network connection after the screensaver has been running and will have to us the XP network repair wizard to re-connect. I have also started having problems losing the focus in the logon prompt on the XP logon screen. The only way to get it back is to reboot the system. Are these known issues, and are there any ideas on how to deal with these?

Operating System:Windows XP Pro
Software Version:7.0
