AVG security

Nothing to do with birding but if any forum users have AVG security installed on their computer and if so have they had any problems recently.I keep getting messages that the system needs updating and needs to shut down to do so only to get the message that it was unsuccessful so after a day of this I have uninstalled AVG.Any suggestions you techies out there?
