Behavior Shield doesn't turn on at startup

Very rarely does this not happen, but most of the time when i start my computer (Windows 7 Professional 64-bit for info), I have to manually turn on the Behavior Shield. I went to settings>compopnents>behavior shield>customize and see if there was an option to change this but there isn’t. Is there any way I can fix this?

Are you running the latest version ???

yes latest update version 18.1.2326 build 18.1.3800.0 latest definitions 180226-4

Try the following:

Repair Avast:
Control Panel> Program and Features (Add/remove program)>Select Avast> Select Repair. Reboot when completed

If Repair doesn’t fix the problem, try the following:
Clean Install of Avast:

Instead of posting a link to some .gif file, it would be helpful to post information about your system.
