Avast IS version 7.0.1426 running on Windows Vista Home Premium SP2, logged into a “standard” (non-admin) user account.
If I force a program update form the user interface, maintenance section, it checks for an updated version, determines that I am on the latest version, but still prompts me to reboot the computer. I am sure that it didn’t used to do this, and I cannot see that it should be intended.
