How do you set AVAST to automatically delete/move virus to chest?

I keep getting the message that i have a virus that wont go away , well its 2 of them and the menu that asks me if i wasn’t to delete or move to chest, well every time I delete or move to chest it always pops up again , and it interrupts whatever I’m doing, I was wondering if theres anyway to set it to automatic because its getting really annoying,

that or is there a simpler way to get rid of the virus
its the same one as this

and theres one that pops up right after this one , its
Ossproxy.exe

Unless you want spam, please remove your email address.

Deletion is not good. Send to chest, do no harm.

Ossproxy.exe is foistware and adware.

I suggest:
