no experience with 360 total security but using avira & it is working fine except for one minor issue for me.it seems that some avira updates require restart of pc but you will not get any prompt to restart,you will only notice it when updates start failing & log show "engine validation" error.only way i know for this issue is restarting/shut down pc every day instead of keeping it on/hibernation/not restarting for days(i sometimes don't restart my laptop for days but use hibernate to power off).
