This is what I got when I opened avast settings(the "no such file...") and what I got after activating web shield:
Nov 29 13:02:25 dyn-218-048 [0x0-0x3f03f].com.apple.systempreferences[677]: Error opening configuration file: No such file or directory
Nov 29 13:02:43 dyn-218-048 authexec[691]: executing /bin/mv

This is what I get when I'm trying to open a website when web shield is active:
Nov 29 13:11:52 dyn-218-048 proxy[65]: Error creating connection socket: socket(): Too many open files
Nov 29 13:12:22: --- last message repeated 4 times ---
And this is what I get when I'm deactivating web shield:
Nov 29 13:12:50 dyn-218-048 authexec[774]: executing /bin/mv
Nov 29 13:12:51 dyn-218-048 authexec[775]: executing /bin/kill
Nov 29 13:12:51 dyn-218-048 proxy[65]: SIGHUP received. Restarting.
