Antimalware, firewall, and other security programs for Windows XP working in 2023 and hopefully beyond

As its stated minimum system requirement is Windows 8, I would be very surprised if it works on XP.

I'll be delighted if I'm proved wrong though!

When you click on "Minimum" system requirements, it lists "Internet Explorer® version 11 and newer (Windows XP IE8)", so that's confusing.

Almost all the quoted browser requirements are ancient! 🤔

My ancient version of Kaspersky under Windows 10

This thread is about anti-malware programmes under Windows XP. BTW, there is definitely no need to use an "ancient version of whatever" under Windows 10. And talking about your "ancient version" is like "beating a dead horse". 
A version of this programme running under Windows XP has not been available for a long time. And it gets even worse: the programme is not secure, and its country of origin is beyond good and evil. In my next article, I will post something current for Windows XP.

There are now (at the end of 2025) very, very few anti-malware programmes for Windows XP with real-time protection free of charge. Panda Free Antivirus is an absolute exception. It is still maintained and runs under Windows XP. Here are two screenshots of the current version 22.03.05, which has just been released:

An anti-malware programme with a most recent scan engine and up-to-date virus definitions even under very old OSes like Windows XP or Windows Vista. What more could be wanted?

Panda Free Antivirus

AstroSkipper ... Just came across you're updated information dealing with Windows XP and Panda Free Antivirus. Around two weeks ago I was actually looking for any antivirus programs still working with WinXP in 2025. Didn't find any after doing a quick search on some programs that worked many years ago and reading your earlier post on the subject.

Thanks again for the update on this valuable information for Windows XP users.

Panda Free Antivirus

Ran into a small problem after downloading your 'offline installer' download. I got offline to run the download and found out that I need to have .NET Framework also installed. I did have .NET Framework 2.0 installed years ago but removed it. Didn't seem to have much use for it on Win XP at the time. If there were any programs that might require it I was always able to find another program that didn't need .NET Framework to run.

I have all the .NET Framework versions that worked on XP stored on a DVD backup with other old Win XP programs ... in case needed one day. I think at the time .NET Framework 3.5 was the last version to work on XP but after getting back online to search around I now see that there is a .NET Framework 4.0 that will install on Win XP SP3. I have now downloaded that version but I may just try .NET Framework 2.0 first out of curiosity and see if that works. If not then I can jump to version 4.0. That version from MS is dated from last year: 07/15/2024 ... I will put the MS link here in case someone else has need for it.
