Greetings, yesterday I started getting a Windows Security Center (XP Media Center) message saying Avast is reporting that it is not current. I've updated the program and virus files, installed an updated key, uninstalled Avaste and downloaded new program (5.0, I didn't realize there was a new version), defragmented the hard drive, checked for errors. The Avast says I'm secure. How shall I proceed? Thanks, Steve
