Problem Similar To Avast Loopback Issue??

Hi guys.I have a problem with Avast 7xx1474 and CIS 6.
I try to explain step by step:
1-If I set IE Proxy settings to for example : Localhost:Port
2-And I run a program that handles traffic through this Address:Port
3-Then run a program that is Blocked by CIS but this program by default uses the IE proxy to connecting.
4-CIS reports Blocked in Firewall Log but program can still connect.
5-Also if using programs like Proxifier,Sockscap,etc. CIS reports Blocked but program can connect.
-By uninstalling Avast everything is ok.
What can do for this issue?
