If it was suspicious of it why hasn’t it blocked it?

I have avast working at it’s default settings, I’ve never had the need to change any of them. I do not have it set to ask to my knowledge and avast never alerted me to it as being a “suspicious” file. I simply noted it on the behaviour shield and was curious as setup and .exe popping up in the behaviour shield just had me curious (and maybe concerned).

I wasn’t installing a program yesterday but it could have been updates, I’ve just never really noticed that particular activity in the behaviour shield before, for all I know it could have happened whoever knows how many times. Hard to pinpoint the when it appeared just know it was 1 of 3 yesterday before I shutdown.
