It’s old news now, new for me, worth mentioning, though. Clamwin, the free Windows antivirus does work under Vista. The installation went smoothly, which was to be expected. The software still needs quite a bit of work in a number of areas relating to the user interface and OS integration (looks like Windows 2000).
There are a few minor bits that I picked up so far: being asked to integrate with Outlook on installation, choosing not to and finding after installation that in the preferences, email scanning of Outlook outgoing and incoming emails are both checked. It doesn’t seem to integrate with the Windows Security Center, which translates in Vista still complaining that “Virus protection” is off. This can be turned off by selecting manual monitoring of the antivirus under Windows Security Center, but it spoils the good feeling you get from an application that integrates fully with your OS. A really good antivirus, still.
