Hi, Leo. I was wondering if I should download a firewall. My Windows
firewall is disabled, turned off, and it wonât let me turn it back on or use
the recommended settings. I was thinking about downloading a firewall since
this is important. Do you think it will harm my computer to download one? I
know youâre not supposed to have more than one firewall running â as they can
conflict with each other and cause the computer harm and to crash. But since
itâs disabled and wonât turn back on, I didnât figure it would hurt since it
wouldnât be the same as using one anyway, because the other is permanently
disabled. What do you think?
In this excerpt from
Answercast #51, I look at a system that has disabled the Windows firewall.
This is a symptom of malware.

Disabled firewall
I think youâve got a bigger problem.
I think the solution here is definitely not to install another firewall.
Sure, you can, it may not harm anything. My typical recommendation, instead, is
just to rely on the firewall that your router provides â but thatâs neither
here nor there.
My real concern here is the fact that you canât turn the Windows firewall
on. Thatâs bad. That is something that needs to get fixed.
Symptom of malware
The reason I say that is because this is one of the symptoms of malware.
Malware will often go through extra steps to disable things, like your
firewall, and make it impossible to turn on. They will often also disable your
anti-malware software and make it impossible to get updates for that.
So, my very strong recommendation is that, for the the moment, you forget
this additional firewall issue and instead â focus on clearing what is likely
to be some kind of malware infection on your machine.
Check for viruses
-
Consider running the free tool from Malwarebytes.org and see if you canât
clear up whatever is preventing the firewall from being able to be turned
on.
Once you fix that, well, then the whole issue becomes kind of moot. You turn
on the firewall, the Windows firewall and youâre good to go.
And like I said, even then if youâre behind a router, in my opinion, youâre
actually safe enough leaving the firewall turned off. But the fact that you
canât turn it on, well, that is a problem and thatâs a problem I think that
needs to be addressed.
Next from Answercast 51 â Canât we just charge spammers per email they send?
I agree with Leo 100% that there is a bigger problem and that it is almost certainly a virus issue. If you want a really good firewall, I highly recommend Comodo Pro Firewall. Itâs much better than Windows firewall (which only blocks âincomingâ threats). Comodo blocks incoming AND outgoing threats (If some virus does get your info, it canât send it out of the computer without your permission). I also highly recommend Emsisoft Ant-malware and as Leo said, Malwarebytes. Just be sure to choose âfreeware modeâ when setting up Emsisoft (keeps it free, which is a good enough version for most) or you will only get a 30-day trial. Good Luck!
Not necessarily. If you install Microsoft Security Essentials, it will disable Windows Defender to avoid conflicts.
If youâre not running MSE, then I agree!
If there is no malware found, then there is a possibility that you have a problem with your Windows implementation. How you handle that will depend on what version of Windows you are running.
I have spent much time trying to remove Windows Operating System corruption issues caused by criminal-ware.
I have found it is usually quicker to âbite the bulletâ & install Windows
