AVG Antivirus not updating

I have received a notification that my software is not up to date. I press update now. I am connected to the internet. The program thinks about it for a while, then tells me that I am not up to date. It doesn't seem to be fetching the required updates. I have restarted computer. Any advice?

Hello Michelle,

Sorry for inconvenience caused. Are you using a paid or free version of AVG program? Please let us know the 'Operating system' of the device you have installed your AVG program.

Thank you.

Hello Michelle.
Pleased to see that you appear to be now sorted. Thanks for returning to the Community & posting.

Hi. I'm on Mac OS so it is a free version. Mac OS X Yosemite, Version 10.10.5. After checking for updates about 30 times in the past day, getting the same result, I have just done it again to give you the exacting wording of what happens and - wouldn't you know it - it installed the updates and now indicates it is up to date. Problem solved. I did nothing differently, but whatever the glitch was, it has sorted itself out. Thank you for responding.
