Why 2 icons? PC Tune Up & 1 click maintenance

when you want to clean (or fix .etc)  your pc automotically to use the 1 Click
when you want to do sth with your pc or use some senior tools, open  the PC TuneUp and select tools by your self

I just installed AVG 2014 PC Tune Up.  Now I've got 2 different icons on my laptop.  One is for PC Tune Up and the other is for 1 Click Maintenance.  What is the difference? 

When am I supposed to choose PC Tune Up and when should I choose 1 Click Maintenance? 

HELP!
