I installed AVG 2015 for the free one month trial and as the period ended I attempted to uninstall and change to AVG Free. Received error code 0xC0070643.  Item failed to uninstall or change - what next please?

Derek, Try removing AVG by downloading & using the 32 or 64bit 2015 Remover (http://www.avg.com/ww-en/utilities) [Scroll Down], whichever suits your system. If you're not sure about 32 or 64 bit on your system have a look @ this link (http://forums.avg.com/ww-en/avg-free-forum?sec=thread&act=show&id=140471#post_140471).
