comodo free broke my windows home server and i need help fixing it please

Hi All,

I installed and ran Comodo on my WHS machine and the first thing i noticed was that my client machines werent able to read their user profiles…so my mail clients and desktop and view settings etc were all missing.

this terrified me so i tried the standard uninstall from the WHS machine. it seemed to work ok.

when it restarted, it gave a service error and also tried to throw a call to a windows.ini file, plus comodo was still present in the programs registry.

it still had the “uninstall” executable via the programs panel, so i tried to run it, under admin, normal, and safe mode- to no avail.

i then downloaded CFP removal tool and that seemed to work…but again after restart no joy.

i manually removed most- but couldnt remove all registry values…as my clients are still uanble to read their settings files. it isnt a corrupt user file either as they work fine if i disconnect the network.

So, despite it seeming to rid the program, it is still there, and still messing up my entire network.

after this experience, id like to rid comodo entirely and put my network back to how it was.

its cost me about 3 hours so far…i would like to know how to remove it please?- ive tried to reinstall, but that doesnt work either!!!..

ive read through the other problems many are having…but without user profiles i cant system restore either…

i hope someone from comodo or the community can assist as im at a loss now…and still with this issue remaining.



Welcome to the forum tnewman72

I installed and ran Comodo on my WHS machine and the first thing i noticed was that my client machines werent able to read their user my mail clients and desktop and view settings etc were all missing.

Unfortunately, this was likely due to incorrect configuration. Did you create rules to allow your clients to connect and retrieve their settings?

Can you explain, exactly, what happens now when you try to connect to the server from a client?

thats the beauty of WHS- it is simplified so all of such tasks are done for you- if done at all. I havent created any rules…just purely installed it on the server and my clients.

its been working like a charm until comodo got its talons into it.

I think you’ve missed the point anyway…how do i remove Comodo when all the other suggestions dont work?

Surely this thing was tested on WHS and full removal confirmed and validatedf on all systems prior to be letting loose into the public domain?- ive seen hundreds of similar reports with people having to reinstall their OS’s and go to great lengths to find workarounds.

so- how do i remove comodo?..completely?..without haivngt t o use system restore, or reformat my drives.?

Unfortunately, missed my point also. The reason your clients were unable to connect to your server post installation, is probably because you didn’t create rules in CIS to allow them to do so.

The only thing I can suggest now is you try the following:

Uninstall CIS and reboot. Then run Comodo System Cleaner to get rid off registry keys.

Then delete the Comodo folders under Program Files, Program Files\Common Files, C:\Documents and Settings\All Users\Application Data\ .
For Vista/Win7
Users%username%\appdata\local, Users%username%\appdata\roaming\ and \Users%username%\appdata\local\virtual store

To be even more thorough open Device Manager and set it to show hidden devices under menu option View. Then see if there are Comodo driver(s) left in non Plug and Play drivers. If so select the driver → click right → uninstall and reboot.

Now delete the following:
C:\boot.ini.comodofirewall (this file may not exist).

*Note: It may not be possible to remove these “LEGACY” keys. If you cannot delete them, leave them in the registry. However, I have subsequently found that you MAY be able to remove these keys in Safe Mode by using a third-party registry tool. To permanently remove them may also require modifying the Permissions for each key. See:;msg119226#msg119226

The OP is dissatisfied with CIS on his WHS system and has reinstalled the O/S to remove CIS.
