    Comodo failed to uninstall

    When I switched on the PC this morning there was a popup from Comodo about a new local area network. I was requested to give it a name and authorise it.

    As I have not created any new networks, and my wife wouldn’t know how to, it struck me as dangerous and so I blocked it. This was a mistake, as it was then impossible to access email or the internet.

    After a fruitless period spent trying to amend Comodo - it’s too technical for me – it seemed that the solution would be to remove and reinstall it. But the uninstall failed with the message ‘Network Error. C|WINDOWS\Installer\CFP_Setup.msi’. Attempts with Control Panel’s Add & Remove programmes, Absolute Uninstaller and Comodo’s own uninstaller all failed.

    However, part of the programme had been removed, as the icons on desktop and task bar had gone and it was now possible to access the internet. This enabled me to get on with some work for an hour or so, hoping that the router and Avira premium would protect me, as clearly Comodo was not fully functional. Something called Geek Buddy had been added and kept unsuccessfully trying to update.

    Returning to the problem, another attempt to remove the firewall failed, so it seemed that as it was not functioning fully it might be possible to install ZoneAlarm as a temporary measure. This was a disaster!

    All went well until ZA scanned the pc and failed, leaving two partially installed firewalls. ZA and Geek Buddy both kept asking for an error report, which could not be sent as internet access was lost. Plus a series of pop-ups said Clipmagic had encountered a problem and would close, followed by similar from Secunia PSI, explorer.exe, Netgear and others.

    By this stage the PC was unusable, it was impossible to access my files to see how to enter Safe Mode, but I seemed to remember it was P5 or P6. My guess of P5 was correct, I succeeded in removing ZA but not Comodo.

    Internet access was restored and the PC usable, just the question of how well Comodo functions. There seem to be two options;

    1. Geek Buddy finally installed and updated once ZA was removed. The terms state there is an annual fee, without specifying the amount. It would also involve the rip off charge that credit cards make on foreign currency exchanges. But I assume they would know how I should proceed.

    2. An easier option would be delete Comodo from the programmes folder, but is this safe? A reinstall might mitigate any harmful effects, but I do not know.

    Any suggestions gratefully received, as I’m not sure how secure the existing situation is. Certainly tomorrow I will be making several scans to see what I may have picked up in the meantime.

    I suppose you could try a repair install of Win 7. to correct the basic Win 7 problems. This is an ideal place where an Up To Date Image would have saved your bacon in about 10 minutes. There are many threads on Imaging in this forum.

    I would also use an uninstaller such as Revo Uninstaller to help completely uninstall apps.

    In your case, your OS may be hosed enough that you have to reinstall Win 7, sorry.

    Ted, once again thanks for your help.

    I forgot to mention in the posting that my OS is Windows XP, which to the best of my knowledge doesn’t have a repair install function. Even if it did it probably would not have helped, as the problem is within Comodo itself, as System Restore did not find any changes to restore.

    I downloaded Revo Uninstaller, but it was no more successful than the others. In fact it opened the Comodo uninstaller, which failed with the same message as before, rolled back the changes, then Revo took over again and started removing remnants from the registry, etc. Suddenly it struck me that this could make the matter worse, so I stopped the process via task manager.

    Yes, I intend to get an external hard drive and an imaging programme, but unfortunately have been too busy to get round to it. I really must do so, as it would have saved more time than I’ve already spent on this, and I’m resigned to the fact that it is going to need a reformat to remove Comodo.

    Scanning with Malwarebytes and Superantispyware failed to find any infection, so the system seems to be clean so far, and is working normally. The only problem is not knowing whether Comodo is providing any protection, thus forcing me to use the laptop instead.

    Ted, you might be able to answer two questions for me.

    1. How safe is it to just delete the Comodo folder from C\Program files?

    2. Does one really need a software firewall, or is the router’s firewall, along with Avira premium sufficient?

    Failing a favourable answer here, it’s sign up to Geek Buddy, then probably a reformat to get rid of Comodo.

    Regards

    George

    I have tried reinstalling several times, at least once per day, but it always gives up after failing to remove the existing version. However, I will try again later, in the sequence you suggest, but Avira is about to start the daily scan in 12 mins. time.

    Zig, is there any chance you know the answer to either of my questions in posting #4

    1) You can delete the folder, but this will not solve your problems. You might try CCleaner (Registry cleaner) to clean up orphaned entries after deleting the folder. I suspect some of these orphaned entries are causing your problems. Entries can be cleaned up manually using registry editor (Regedit.exe) and manually searching for Comodo entries. I would do this after deleting all folders for Comodo, then using CCleaner to clean up everything it can find. Before starting any of this back up the registry!

    2) Yes a software firewall is another layer of protection that most consider essential. This is especially true in XP since it is much less secure than Win 7.

    Is the only way to back up the registry in XP via System Restore, as instructed in Ted's link?

    It would be safer if one could have it on a memory stick, in case system restore will not open, as has happened sometimes in the past when I've had major problems.

    You can back up the XP registry using a program called ERUNT.

    I have completed my end of tax year accounts, backed up my docs and Sharescope and installed Erunt, so am ready to manually remove Comodo. But do I want to reinstall it?

    Is there another effective firewall better suited to my non technical abilities? I only needed to remove it because I made the wrong choice when it found a new local area network, and there appeared to be no other way to reverse my decision.

    Preferably not Zonealarm which caused me a great deal of hassle a year or so ago, but one did have rather more idea of what applications were allowed than with Comodo, and decisions could be changed.

    Hello georgelee,

    I have used Online Armor Free Personal Firewall on XP and have been very pleased with it. I also tried Comodo for a time, but I did not like it because it pestered me all the time. Online Armor, at least when I used XP as my preferred OS, was much less hassle, yet it blocked outgoing processes unless or until I approved them.

    I like Online Armor better than any other firewall I have used on XP. On Vista and Windows 7, I use the Windows Firewall, but it is much improved over the XP firewall. Also, if you try Online Armor and like it, and you eventually move to Windows 7, Online Armor can cover you as it is compatible with 32 and 64 bit Windows 7.
