[dba-Tech] Avg Anti-Virus

I've been using AVG Anti-Virus Free Edition for about a year. Several days
ago the Update Manager refused to turn red after rebooting. Now, I can't
update. I try, but they're always unsuccessful. I've rebooted several times,
but the Update Manager simply won't update itself. 

Since it's the free version, I'm sure there's no support for it. 

Has anyone ever run into this?
