Free version provides HIPS & Firewall protection. I installed it on high auto allow and added
1. Allow folder rules for Windows, Program Files and Windows Defender (in ProgramData)
2. Deny folder rules for all non-Microsoft programs (and user/AppData/programs), with WD ASR and Exploit protection (Code Integrity Guard) Microsoft programs are sufficiently protected, HIPS protection adds a nice layer for non-M$ programs.
3. Allow rule for inbound (still using Windows FW for inbound with outbound blocks from H_C/Firewall Hardening
4. SpyShelter takes care of outbound with auto allow on high
5. Allow non-M$ programs to go outbound (like Opera). Only hassle is that I have to allow each new version of opera (I guess). Because I still use FirewallHardening for M$ programs within WindowsFW these M$ programs are blocked by Windows Firewall
So Windows programs are managed by Windows programs (using Hard Configurator, Defender Configurator and Firewall_Hardening) and non M$ programs are monitored by SpyShelter. I know it is not supposed to use this way, but together with Hard_Configurator and WD on MAX it works great (Yes I replaced Kaspersky free with WD again
)
I wait a Windows and a Opera update and when it does not throw a popup, I will enable auto-block suspicious behavior
