Avast version 6.0.1367 not working

Avast version 6.0.1367

Hi
My avast internet security has not been working for several days now.
I have done nothing different to the computer, and when I go onto Avast and press the FIX NOW button,
it simply requests permission from user account, and does nothing else, going round in a loop.
similar happens when I press the start programme button.
It states - URGENT: avast! service stopped.
what is the reason for this please and can you help me get this back on asap, as I am not protected. :frowning:

Use the uninstall utility see here:
www.avast.com/uninstall-utility

We have a fresh version 7 out now…

after fully removing version 6 download and install version 7 from here:
