I've been using Comodo Firewall for a few years. I installed Evorim today and it works just fine alongside Comodo FW.
That seems pointless - right? Well consider the following:
Once installed Evorim's startup entry can be removed. Also the firewallsvce can be stopped (when Evorim FW is not running) and set to demand start.
That takes care of memory usage issues especially if you
use Evorim FW as "run on demand" only.
Run On Demand is the way that I'd use it.
It displays a list of firewall rules of what is currently blocked/ allowed/ not configured.
It also displays a list of active connections.
Inspecting the list of allowed entries (easy to read and understand) it became clear that there were a few items that I needed to block.
I blocked desired entries using Comodo FW then refreshed Evorim FW listing as a double check.
When happy - I shut down Evorim.
I'd say it's actually a
very useful way to double check your existing firewall.
RE: Telemetry blocking.
Personally I avoided any Windows 7 telemetry related updates. Also:
Open Task Scheduler. Under Task Scheduler Library > Microsoft delete the following items:
Everything under “Application Experience”
Everything under “Autochk”
Everything under “Customer Experience Improvement Program”
Under “Disk Diagnostic” delete only the “Microsoft-Windows-DiskDiagnosticDataCollector”
Under “Maintenance” “WinSAT”
“Media Center” and click the “status” column, then select all non-disabled entries and disable them.
I don't use Defender and keep it disabled. I also disable Spynet.
As for the hosts file "block telemetry" methods - well I implemented those but they don't work where MS might have coded telemetry to bypass host file blocking.
So I remapped routing table to re-route MS telemetry related packets to a non-existent ip address.
Use Elevated Command Prompt > Powershell.
