Anti-virus protection - suggestions, alternatives to AVG etc

I did ask a year ago, but as there was no response and as AVG has become a total nightmare and I'm not paying for such a bloated and unwieldly product which keeps pestering me for more info and to do all kinds of things I don't want to do - well, does anyone have any suggestions on what else is out there that is either free and good or is not too expensive and good?

 

I've currently got AVG sitting with an ! over the taskbar icon saying there is an error and when I click on it, there is no error at all - it just wants me to upgrade to find out what else I can find out about AVG- at a cost.

 

Appalling practice.

 

So, any suggestions would be muchly appreciated.
