Change of location in the VPN

Greetings,

You needn't worry, we'll certainly look into this and help you.
Please let us know if you had the "Optimal Location" set as your AVG Secure VPN server/location.
Awaiting your response.

How come is it possible that my VPN location was changed  without my knowledge to Petersburg Russia? 
I changed now my password and ran wide security scanning.
Should I still  be worried - and  should I still do something else?

Thank you for writing back to us, Sirkka.

This isn't the expected behaviour of AVG Secure VPN.
In this case, we request you to reinstall your AVG Secure VPN once & check if the issue persists.
We've sent you an email with further instructions. Please check your inbox/spam folders for the email and use it to revert to us.

I do not know what is "Optimal Location"- there i no such option in my VPN.  I use location Finland - but very often when I open my PC or laptop VPN is not on at all.  It should  functionautomatically but that is not always the case.
