AVG frequentky will not open at lap top start up

For the last 6 to 8 weeks AVG security will not start when I switch on the lap top.  I am running windows 10, AVG security and tune up, free Malwarebytes and office 365.
The error message on the AVG security screen is 'well this is embarrassing, it seems we can not start AVG, please retry'.  When I do I get the same error message.  The only way to get AVG started is to do a hard reboot.  An the, there is always a yellow warning icon the AVG logo in the toolbar always asking me to buy secure VPN.
It looks like there is a system problem.  Any help much appreciated.
