AVG free out of date

I am always being told that AVG needs to be updated.  When I try to do the update it does not work.  This has been an ongoing problem and I have asked this question before on the same subject.  I have uninstalled AVG free numerous times and the re-installed it as per the instructions I was given back in July 2017.  Is this always happening because I am using AVG free??  I want my computer protected all the time.
