Perform a repair of avast, if that doesn’t solve it perform a clean installation and check again.

Hi
Thanks for all your answers, i have run avast repair re-booted system still same problem. followed you tube video and download removal tool reinstalled a brand new copy and still Avast will not start on its own after re-boot.It does start manually but same error message still shows but then the scans and anti virus seems to work normally.
Do you think its OK to still use Avast as my sole protection with all the autostart issues.
Once again thank you all for your help i really appreciate it.
