Defense + would interact with the user, the sandbox is off and only when the application is unknown;
The firewall allowed a connection coming from outside to come a secure application (input and output is permitted, but not only that as demonstrated in previous videos). For some reason the firewalls do not filter certain types of leakage;
These failures are not excluisividade the CIS, but all other suites, whether paid or free. >:-D
all reported fixed.
I split and merged this post with CIS Certifications, Test Results & Reviews.
At liosant and taleblou. This topic is only for feedback why CIS was uninstalled and nothing else. And we are keeping it that way. Commenting on the fixes is a rare deviation and mod’s privilege only.
The Geekbuddy bug was fixed and the installer of CIS was updated with that version:
The fixes of the bugs found by Tavis Ormandy are found in Comodo Internet Security 8.2.0.4978 fixes build is released!!!
All bugs reported by Tavis Ormandy were fixed including the GB bug.
Hi,
I am very sorry to leave COMODO. For about 6 years it was my favourite , but now i have to leave.
I hope you have a suggestion to bring me back to COMODO.
The reason is the following: COMODO is not compatible with “Cyber ghost”.
When cyberghost is running, the firewall of CIS is not working properly!!!
Sorry, i am very sad, please give me a solution of this problem and I love to come back.
Thank you Melih, Comodo is the best, but to my mind, not compatible with Cyberghost.
I hope you have a solution.
Believe me, it is very, very, very sad to leave.
Yours forever

Truly amazing. It was almost a year ago (this month) that I wrote that post. Why I uninstalled CIS. It sucks. Still my opinion.
The amazing part? Not a single reply. Not one. I noticed others who posted their reasons got responses.
I will never return to being a Comodo CIS customer.
In fact, I believe they owe me a laptop.

I did not want to stop running Comodo, but …
New UEFI system + Win 10 1607 build + clean install …
Too much hassle trying to get it running on the above.
Hello seeker2k,
We will have a hotfix for CIS 8.4 soon, currently working on getting the drivers signed.
For your information

Here is why I’m uninstalling CIS.
https://forums.comodo.com/-t116679.0.html
I feel Comodo doesn’t care about my files.
Hi, I’m a user since many years. Now with the clean Win 10 installation Comodo CIS isn’t working properly anymore.
Do you have any idea when the hotfix is available?
Now I’m suffering since begin August with unsigned drivers.
Thank you.
We don’t respond to help question in this topic. This topic is meant only for people to tell why they uninstalled. The answer to your question can be found here. Please continue the conversation there.
I uninstalled CIS because Windows defender was much better, caught threats missed by Comodo, and didn’t hog my PC resources. Also, Windows defender is much more stable/reliable than CIS.
I hope that will be going better with next release.
It’s actually very nice software.
Reading this, remembered me, - another reason why I need sometimes to un/reinstall:

Hi,
I like COMODO Internet Security FREE A LOT, but unfortunately I have uninstalled it, because after I did a fresh and clean install of Windows 10 version 1067, I also did a fresh clean install of Comodo Internet Security FREE.
After I did a full system scan the results came back saying that it found a virus/ worm which I marked as a false positive as everything was a clean install.
The reasons I uninstalled COMODO INTERNET SECURITY FREE are as follows:
After I did a full system scan the results came back with a virus being found, after I did the recommended action which clean, after that I did another full system scan and the second full scan took 2 mins as apposed to between 45 mins to 1 hour.
The default update time to check for Virus Definitions is 6 hours, but I found that no updates were received after 14 to 18 hours.
I then did a manual update and it said everything was update, I then looked at the last updates received was 18 hours.
I then had to keep uninstalling and reinstalling CIS FREE (CLEAN INSTALLS) to make sure I received the latest updates. 
I set CIS to scan automatically on a certain day at a certain time, but the automatic scan settings do not work at all (for me anyway).
The (so called Virus/ worm) CIS found was actually my desktop background, after doing another clean install of Windows 10 I installed another FREE AV and no viruses have been found on my system.
I would like to use CIS FREE again, but I am worried because it will not update automatically and it would find a legit program has a virus when in fact it does not have a virus.
Hope my feedback helps.
Kind Regards

Windows 7 Home Premium SP1 x64:
Have used CIS for the last few years, but last night I uninstalled it for the second, final time and moved to an alternative.
I was happy with CIS 8 up until the September 8.4.0.5165 release; there was one ongoing annoying issue right from my first ever install of CIS - if I didn’t wait about 3 minutes at the login screen after a start/-re-start before logging in I’d get an error message from Comodo about being unable to start the Comodo Agent, would I like to run the Comodo diagnostic tool … which would always say there was no problem found, and then I’d have to start Comodo manually - but I was prepared to live with that. But 8.4.0.5165 was a complete disaster: completely unusable for me as after installing it I couldn’t use my computer at all - BSOD crash at the Windows log-in screen every time. Only way I found to get the computer back was to start it in safe mode and use system restore to go back to before the CIS 8.4.0.5165 install. This was completely repeatable. While I was happy with 8.4.0.5076 as such, if there’s one type of software I like to be up to date it’s security software, so I waited anxiously, hoping a further CIS 8 release would solve the problem. But there wasn’t a further CIS 8 release … there was CIS 10 instead.
So I saved my (,5076) CIS 8 configuration, installed CIS 10, and unlike after an 8.4.0.5165 install, I could log into the computer without a BSOD. So I imported my last CIS 8 configuration and … all the trouble started.
Two main issues with CIS 10.
Somehow it kept forcing the computer into a basic, non-Aero theme, with the desktop theme manager ‘unavailable’ despite the fact that the service was running and there was plenty of memory and low cpu usage. All access to Aero themes and features gone. At first I seemed to find that if I disabled at least one CIS 10 component out of Firewall, antivirus, HIPS or viruscope, then on start/re-start I got my Aero themes back, so I disabled viruscope … but it turned out to be inconsistent - sometimes I had to disable 2 of the modules, sometimes 3. Clearly this is not an acceptable situation.
With at least Virsucope disabled to get my Aero themes back (though eventually that turned out not to be consistent), I hit the second problem. Browsing in Firefox, going to any page that had Flash or Silverlight content on it (which I don’t always know in advance, and some important sites to me use them) the Firefox loading of the page would hang, the little animated ‘wait’ circle going on and on, repeated appearances of the ‘plug-in not responding, it may be busy or have crashed, stop plug-in or wait?’ dialogue for at least two minutes, sometimes as many as five minutes before the page would finally finish loading (flash or Silverlight now working) and allow me to continue (and this completely held up Firefox while it was happening, couldn’t browse other already loaded tabs while waiting); and it happened EVERY new page opened with Flash or Silverlight content on, not just the first time per session. To be clear: this did not happen with CIS 8.4.0.5076; it did not happen after uninstalling CIS 10; it does not happen with e.g. Avira Free installed instead; but it always happened with CIS 10 installed. Again I initially thought I’d narrowed down the problem and that it cleared if I just disabled HIPS (which on my first testing also seemed to cure the Aero problem), but that turned out not to be consistent either. Sometimes I had to disable the Firewall as well, and on the last occasion it only cleared when i disabled EVERY module in CIS 10. (I did go through trying things with rules and rulesets, creating specific rules that shouldn’t have been necessary for a trusted program etc, but nothing helped.)
(Oh, and 3, the irritating issue with CIS not starting if I didn’t wait 3 minutes after logon, offering a diagnostic that finds no errors and me then having to start it manually was still present in CIS 10 too, just like with CIS 8.)
So - without one or often two or even three modules disabled, CIS 10 dumped me into and held me in a basic non-Aero theme. And without apparently randomly changing modules disabled, browsing became effectively impossible, given that many pages would lock up all of Firefox for 2 to 5 minutes just loading.
So I uninstalled CIS 10, read some reviews and downloaded and installed another antivirus program.
Not quite the end. While I was getting to grips with the replacement (Avira) i thought that maybe, having gone round uninstalling every trace of the Comodo programs before installing Avira, i should try one last time with CIS 10, as a fresh install now, not an upgrade over CIS 8, and with its default settings, not the ones from CIS 8 I’d imported before, then scrambled in my attempts to fix the problems. So I uninstalled Avira, then installed CIS 10 again, fresh and default this time, crossed my fingers, re-started the machine and … CIS 10 had forced the machine back to a basic, non-Aero theme again, and the 2 to 5 minutes Firefox lock-up to load pages with Flash or Silverlight content was back again.
I gave up, and uninstalled CIS 10 for the second, and last time, cleaned up, then re-installed Avira.
I’m not happy. I liked Comodo … if CIS 10 would just work on my machine. And while Avira is unobtrusive and ‘light’ on my machine compared with Comodo, has excellent testing results for effectiveness, and I’ve had no problems I’m aware of, there’s several things about it I don’t much care for … the way it handles things it finds; the time it takes to do a FULL scan (just a few minutes under 24 hours for the one I’ve done so far, even though it’s so resource light I wasn’t aware of it affecting my use of the computer while I was doing it); the hoops one has to jump through to ‘whitelist’ things it thins are or might be malware but which I know aren’t; and the fact that I’ve not got a 3rd party firewall running for the first time since installing ZoneAlarm on my first Windows machine after moving from another, now long dead OS. I’d like to go on with Comodo, but just can’t. Comodo seems to have been made for computer geeks; certainly the diagnostic procedures and bug reporting procedures laid out on the forums are entirely for computer geeks. That once would have been fine for me because I used to be a computer geek. But ten years ago I became disabled, I’m in constant pain, and am constantly and permanently on prescription medications to keep the pain bearable that have side effects of muddling my brain, make it hard to think, concentrate, remember. Just can’t cope with the length and geekiness of pursuing these problems for days and days. Just typing causes rapid increases in pain, and concentrating to type anything coherent increases the pain faster and faster - this has taken a day to type in little bursts, and I’ll pay for it over the next few days. But i wanted to give this account, this info, because I LIKED Comodo, wish you’d fix it so I could go on using it.
I rather suspect that all the devs focus is on CIS 10 working with Windows 10, and some Windows 8 stuff as an afterthought, and you’re not bothering thinking about and testing on Windows 7 much any more. Maybe I can come back when/if i get a new and presumably Windows 10 laptop. But living on only disability benefits that won’t be soon.
I had to uninstall CIS complete because it slowed my system down so badly, it took forever for browser pages to load. I’m convinced it was Geek Buddy that was slowing my PC down. It was always running! The Anti-Virus took forever to update new signatures as well. When I installed just the Firewall and had no problems at all with slowdown or page loading issues on-line.
Hi newcomerD,
Thanks for trying Comodo.
Few points:
After I did a full system scan the results came back saying that it found a virus/ worm which I marked as a false positive as everything was a clean install.Sorry about the false positive. We have it and so every other AV, when you detect some time you mis-detect also. We are trying to improve continuously and have a very active response to reported false-positive as can be seen in this [url=https://forums.comodo.com/av-false-positivenegative-detection-reporting-b154.0/]false-positive[/url] reporting section:
but I found that no updates were received after 14 to 18 hours.Seems there is some misunderstanding here. Comodo checks for updates every six hrs and if there are updates available, it updates. It does not mean that upon every six hrs, it must find some new updates. The reason being, in addition to traditional local av database Comodo also uses cloud, so every detection that is made in back-end, is immediately reflected in clients without requiring local updates. So it does not need to update local database every few minutes.
3. I set CIS to scan automatically on a certain day at a certain time, but the automatic scan settings do not work at all (for me anyway).This should be easy to solve, we can work with you to identify the problem.
I would like to use CIS FREE again, but I am worried because it will not update automatically and it would find a legit program has a virus when in fact it does not have a virus.What Comodo provides is prevention and when you go out and try any other products, they rely on detection, results, you can be infected what they don't detect. So really, there is no alternate to Comodo. We have been working continuously on reducing false-positive and it is a continuous process. Still may you want to share that false-positive with us?
Please see if you can give a try again and we can work out the problems you may have observed e.g. schedule scanning.
Thanks

Hi buttoni,
Did you upgrade from older version or it was a fresh install.
In case it was an upgrade, we suggest to re-install Comodo as there have been problems reported.
In case it was a fresh install, may you please share following details?
Thanks
