@VistaLover The posts about Comodo Antivirus were simply intended to inform Windows XP users that there is still a perfect alternative available. However, Comodo had not deemed it necessary to release an official, static link to the final installer for Windows XP/Vista when it discontinued support for these operating systems. Having learnt from my experience of reviving Malwarebytes Anti-Malware Free/Pro 1.75.0.1300 — regarding the updating of its definitions – I have drawn my own conclusions. I never make the same mistake twice. The Windows XP haters of this world will get no further fuel from me. I will do nothing that might prompt Comodo to pull the plug, as Malwarebytes did back then, even if my fix doesn't modify or patch any Comodo related files and only restores the state that the online update function was actually supposed to carry out. One thing is clear. A cursory search for this installer will get you presumably nowhere; you’ll need to dig a bit deeper in the case of Comodo. However, success is not guaranteed as Comodo generally replaces previous installers with more current ones. Whatever the rules may be. Very often installers are then still advertised to be compatible but they aren't any longer. If you can’t find anything, alternatively, you could make do with the installer of the previous version which is still available. The online update is not essential, as you can update Comodo's definitions offline at any time. The main programme and the VirusScope recognizer DLL files will no longer be updated online anyways, due to the change from SHA-1 to SHA-512 signature. These DLL files can only be updated manually by newer, compatible ones, if any are found, of course. I only restored the online update functionality to see, if it is possible, and due to the fact that I can do such things. It’s just the way I am. Regards, AstroSkipper

Update notification! Malware Hunter has been again updated on 20.07.2026 and is now available in version 1.219.0.863. It is still listed to be compatible with Windows XP. Accordingly, I will update my article to this version. Tests can be done by the users. Cheers, AstroSkipper

In addition to the previous article, I have updated all lists in the second, third and fourth post of this thread to the most recent facts.

How to secure Windows XP in 2026 - A multi-layered security strategy It is now July 2026. Since Panda Security – either unintentionally or perhaps deliberately – rendered its Panda Dome programme unusable on Windows XP from 2 July onwards due to faulty automatic updates, there are, in practical terms, hardly any anti-malware programmes with real-time protection left for this operating system supported by both programme and definition updates. Almost all well-known manufacturers of antivirus and antimalware programmes have discontinued support for Windows XP over the years. It is therefore of the utmost importance, first and foremost, to persuade Panda to correct its update routine on the server side. Windows XP enthusiasts can exert considerable influence here by reporting all issues with Panda Dome to the support team. Only if many people do this is there a realistic chance that anything might change in this regard yet. I really shouldn’t care, since I'm actually done with Panda. In any case, Windows XP users must realise that comprehensive security suites, as they used to be, practically no longer exist. System protection must therefore be organised differently. You have to build and organise it yourself using various tools that must work together harmoniously. Layer by layer, so to speak. What do you need for a secure Windows XP system? Windows XP SP3 with all essential components and available updates. Backup system: A fully functional backup system that regularly creates partition images. Firewall: A very good firewall that monitors all network traffic, including all incoming and outgoing connections, even those from Windows XP system components. Real-time protection: A programme that runs in memory, detects and reports threats. Process manager: Located in the taskbar. Startup manager: A good startup manager. On-demand scanners: One, or better still several, good on-demand scanners with a disinfection feature. Browser: An up-to-date browser with an ad blocker. Certificates: Up-to-date root certificates. And, of course, common sense. And if anyone now claims that this is impossible, I’ll respond directly: I’ve configured my Windows XP system exactly like this and haven’t had a single infection in 25 years. Windows XP is still my main operating system alongside Android. Cheers, AstroSkipper

Comodo Antivirus 12.0.0.6870 - The last version for Windows XP FYI, Comodo Antivirus 12.0.0.6818 is not, in fact, the latest version compatible with Windows XP. Furthermore, it contains various bugs that have been fixed in the actual latest version targeting Windows XP. It is Comodo Antivirus 12.0.0.6870: And in fact, even more bugs have been fixed than those listed in the release notes. Here are some screenshots: This version runs smoothly, quickly and light on resources, and the online updates are working again, of course only after fixing myself, without any errors either. Therefore, this will be my final antimalware programme for Windows XP . I do regret not having revived this antimalware programme sooner.

Eloquentia non est tua vis. And a few other things as well. Only people who are verbally impoverished resort to insults. BTW, nice image, is it supposed to become your new avatar?

Did I say that? No. I said it is not Android related. No more, no less. And the problem is of course that I CAN SEE ME. That never happened before.

And it is not Android related. Here is a screenshot taken from New Moon 28 on my beloved, old Windows XP computer:

Ok. You can't see my username but I can as of today. If I open another browser where I'm not logged into my account, I can't see my username, either. So something must have changed.

For example, this page here:

Not working for me. My setting was 'Hidden" for years. But as of today, I can suddenly see my username. That has never happened before.

As of today, I can see my username right at the bottom of the relevant page, even though I’ve disabled this in my account settings. What on earth is going on now, apart from the MSFN outages that have been going on for over a week? Is this supposed to be a new feature, or has the forum software gone completely haywire?

@Dave-H As you haven’t said anything about the suggestion I put forward so far, I’d like to know whether that’s an option for you, or whether limiting the online updates isn’t an option. You can always restore the cache folder once Panda support gets back to you, though I don’t really expect that to happen.

But if anyone now thinks that Comodo actively supports Windows XP, they are very much mistaken. This company is still advertising Windows XP compatibility, specifically here https://antivirus.comodo.com/security/windows-xp-free-antivirus.php, but for years now, the installer provided has no longer been compatible with XP. It’s completely misleading and simply sloppy. Comodo discontinued support for Windows XP in 2019. Now it’s down entirely to the creativity of Windows XP users to breathe new life into old, discontinued versions. And exactly that was what I did.

At the moment, I am very satisfied with CAV and Vir.IT as both use offline definition files. Comodo's definition file base.cav is nearly 640 MB in size and therefore much pattern inside.
