AVG Password Protection has caused my Apps to disapear from my Start page

The first tech who helped me brought everything back and it worked perfectly until I turned the computer off, then when I restarted it the problem was back.  The second tech who tried to help me was unable to do so and told me it is a Microsoft problem and to go to them.  I was unable to solve the problem through Microsoft. I want someone to fix this problem and cancel my subscription to AVG Password Protection so it does not happen again.  This will be the third attempt.
