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? Here is the link to my updated article: Cheers, AstroSkipper

I use Panda 22.03.01 and on a dual or quad core systems PSANHost upon boot up doesn't really waste any cycles, only swells to ~100MB and then goes down to ~15MB from what I observed in TaskManager. It's been a wonderful replacement for Avast and/or AVG and their treachery of the XP systems after all this data we've shared with them throughout the years.

Here you go, enjoy! Installers.zip

It's my own personal opinion that it was done intentionally so D.Draker's name and maybe a few others, would drop off the 'Popular Contributors' list in time ... which finally happened in the last three weeks, or so. I actually miss his name no longer on the list ... it was interesting watching his 'contributor count' go up and down. I hope I am wrong about the 'topic views' ... but since October nothing, lots of '0s' starting to show up. ...

Generally, Panda Antivirus Free is working under Windows XP, even in the most recent version. However, there are two issues. The first issue which I noticed is the unability to connect to a Panda Dome account. Every time you open the programme interface, you are annoyed by a pop-up window asking you to log in to a Panda Dome account. However, this does not work under Windows XP and ends with an error message. There is no official solution for this error. But I have a solution. It appears to be a TLS problem. A secure connection is required, which Windows XP cannot establish natively. The solution is ProxHTTPSProxy, HTTPSProxy or ProxyMII which you can get in my thread Simply set the proxy in the Panda Antivirus settings and set up your Panda Dome account. Once this is done, Panda will no longer bother you, and the proxy settings can be deleted again. The second issue consists of a delay of several minutes during system start-up. Panda Antivirus needs round about 5 minutes to be completely loaded on my machine. I tried different versions and possible solutions, but nothing helped. Therefore, this issue has been reported by me to Panda's support. We will see what happens. Greetings from Germany, AstroSkipper

I was able to login in with OAth2 using MailNews with an outlook account. I had to go in the config editor and set *general.useragent.compatMode.firefox* to true. Then the Microsoft login page displayed properly and worked. Hope it helps some folks, I am using windows server 2003

At the beginning of my Odyssey, I investigated all folders and registry keys belonging to Panda Dome. Therefore, I also found the location of these background images. Additionally, I analyzed the registry accesses of Panda Dome, in particular with regard to the background images. But I have not yet identified the core of the problem. Unfortunately, it is in my nature to solve problems. The pictures are totally unimportant, but I still have to solve the problem. Especially if it works in my other partition. But in any case, thanks for your efforts!

Revo Uninstaller 2.4.5 is the last free version for Windows XP which is offered as an installer and a portable release. You can get it here: https://www.revouninstaller.com/version-history/. Revo Uninstaller Pro 3.2.1 (installer/portable) is the last paid version for Windows XP. It's a very important tool to get rid of remnants regarding antivirus/antimalware programmes.

I got a reply from Adlice to the supprt ticket I filed in terms of RogueKiller: So what was posted here has been confirmed. RogueKiller's real-time protection was never designed for older operating systems such as Windows XP. But at least we have a scanner that still runs on Windows XP in the latest version.

@nicolaasjan I have attempted to make compatible 64-bit OpenSSL shared libraries using MSYS2. If you would like to test them.

Per abbodi1406, https://github.com/abbodi1406/vcredist#windows-xp-notice Direct link: https://download.visualstudio.microsoft.com/download/pr/566435ac-4e1c-434b-b93f-aecc71e8cffc/0D59EC7FDBF05DE813736BF875CEA5C894FFF4769F60E32E87BD48406BBF0A3A/VC_redist.x86.exe MDL forums reference: https://forums.mydigitallife.net/threads/repack-visual-c-redistributable-runtimes-2020-11-10.76588/page-27#post-1630817 I can confirm that the installer is dual-signed (both SHA1+SHA256), thus it can be verified on XP SP3 (which ONLY supports SHA1 file signatures). As for the installer of version 14.29.30139.0 referenced in the "community.pcgamingwiki.com" site, this has the direct link below (courtesy of abbodi1406): https://download.visualstudio.microsoft.com/download/pr/b929b7fe-5c89-4553-9abe-6324631dcc3a/4C6C420CF4CBF2C9C9ED476E96580AE92A97B2822C21329A2E49E8439AC5AD30/VC_redist.x86.exe but it is only SHA256-signed, so I'm not sure if its signature can be verified under XP SP3 : Just my 2c ...

Just running the proxy in the background doesn't mean it is also used by a programme. What I meant is whether you're running ProxHTTPSProxy system-wide or not. In any case, Panda Dome has to use the proxy. Thats why I had to configure Panda Dome to use it, however, for activation only.

First of all, thanks for uploading the files! I was surprised to learn that there is supposed to be a .NET Framework version 4.0.30320 for Windows XP. I couldn't find anything about it in any official source. In any case, your installer "Microsoft .NET 4.0.30320 Full" is the same one I have, and it has the number 4.0.30319.1. Presumably, at least for Windows XP, there is no version 4.0.30320. You can find out your current version installed with the following command: reg query "HKLM\SOFTWARE\Microsoft\NET Framework Setup\NDP\v4\Full" /v Version The MS Visual C++ 2010 SP1 (10.0.40219.473) installer is indeed the last one you can still get from Microsoft or from abbodi1406. I will try later. In any case, thanks again!

As part of my work on ytBATCH, I have investigated many ffmpeg releases that are supposed to be compatible with Windows XP. These include, for example, the releases from @Reino, sherpya and @autodidact. The relatively new ones from @Reino and @autodidact work well with YouTube. But when it comes to TV streams, it's a completely different story. Their latest ones in particular have considerable problems with TV stream URLs. On my old Windows XP computer, negative performance changes are immediately apparent. FFmpeg 3.4.1 from 2017 is too old and can no longer access TV stream addresses. The newer releases 7.1 from 2024 and 8.1 from 2025 require much more CPU power than before. They are therefore problematic for older, weak Windows XP computers. That's why I still have been using ffmpeg releases from 2019 for TV stream addresses.

I believe in those numbers, as I already stated, I don't trust someone will perform the fake scheme you just described. People have things in life, apart from the forum, you know! Besides, it's easy to check, as I already stated, too! So what? It's my business in what to believe. But at this point, it's too obvious you're very annoyed with someone else's fame. I also think there was a hidden reason to disable topic views. As already stated by @Monroe. Otherwise they would've gotten them back by this time already.

Yes. All builds of ytdlp-silent-xp.exe have been tested by me on my Windows XP computer. Unfortunately, none of them are working, not even the latest.

For anyone who isn't familiar with LUA scripts. My mod of the LUA script yt-dlp4vlc does the following: YouTube links entered in VLC are now processed by the YouTube downloader yt-dlp and are then transferred to VLC and played back. Credits to FalloNero. The console window is hidden either by a PowerShell command or by the tool hidecon if the latter exists in VLC's programme folder. Video links without appended quality parameter can now be played again with the quality preset by the user in the VLC settings. The default video codec has been preset by me to h264 so that even older hardware is supported. This can of course be changed in the script by the users according to their needs.

@DesWer on GitHub in the Rumble thread asked me for a link to my Python for XP environment. Well, here it is, complete with all current dependencies installed: Python311_XP-folder.7z Extract it to e.g. C:\Python311 and add that folder, plus C:\Python311\Scripts to your PATH. Instead of building the standalone executable with PyInstaller, you can use pip to install the Nightly build directly: python -m pip install -U --pre "yt-dlp[default]" That will install/update the dependencies as well. (yt-dlp Nightly from 2026.01.02 is already included)

The old download link I used in my ytBATCH releases was https://github.com/nicolaasjan/yt-dlp/releases/latest/download/yt-dlp_x86_Windows-XP.zip which is no longer working. As you can see, at some point you changed the file name of the ZIP archive. For me. no problem. I have already rewritten the yt-dlp update module for the upcoming release of ytBATCH.

hmm, confirmed v30i and v31 also works. and it seems to be broken in v31a and later. since there is no release note and/or changelog for v31a, nothing is known besides ntdll and kernel32 are newer in v31a.

yes it is always an issue because GetLogicalProcessorInformation is missing in XP SP2. you may either update kernel32.dll with that API available(i.e. WindowsXP-KB936235-v2): http://kmeleonbrowser.org/forum/read.php?19,143253,page=10 or patching your target application with kernelxp and patchk32. https://github.com/roytam1/rtoss/tree/master/kernelxp a patched SP52 running on just-installed XP SP2 VM: or unpatched SP52 build on WindowsXP-KB936235-v2-x86-ENU installed XP SP2 VM:

Apparently, I'm not the only one who has noticed such abnormal delays when starting up Panda while system start: 16 minutes! That's record-breaking. Any other here observing similar issues?

If you encounter problems installing Panda Antivirus Free and uninstalling it fails or is incomplete, you should use the Panda Dome Generic Uninstaller, which is available here: https://techsearch.pandasecurity.com/PandaKBView?id=kA1Vr00000064QjKAI

Microsoft .NET Framework 4 is needed and should be installed to ensure that Panda Dome runs correctly.

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. Microsoft .NET Framework 4 (Standalone Installer) https://www.microsoft.com/en-us/download/details.aspx?id=17718 Date Published: 07/15/2024 Supported Operating Systems: Windows 7, Windows 7 SP 1, Windows Vista SP 1, Windows XP SP 3 Windows XP SP3 Windows Vista SP1 or later Windows 7 Windows 7 SP1 Supported Architectures: x86 x64 Thanks ...

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. ...

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.

Personally, I don't expect modern websites that are full of multimedia or completely overloaded to still run in UXP browsers under old OSes like Windows XP, but I am happy about those that still do. All others are called up by me under Android 10 and above. That's why I'm extremely relaxed about the whole thing. The more websites running in New Moon or Serpent, the better, but if not, then that's just the way it is.

Fair enough, as long as the conversation is kept directly relevant to the use of Panda Dome on XP, or indeed any other AV program. Sorry, I have now realised that the details of the .NET 4 updates on Revo Uninstaller are not with the actual installation records, as they are called 'Security Update for....' so appear in a different place in the list! Here they all are, enjoy! The last two images have duplicated entries. Why they all seem to have the same installation date i'm not sure, I don't remember doing an OS reinstallation in February 2019!

As far as I noticed, Panda seems to automatically update the programme only if it is too old. The version 21.01.00 wasn't updated on my system. OTH, the version 18.07.04 was updated to 20.02.01 which, however, isn't the most recent.

Are you running ProxHTTPSProxy in the background by default? And if so, in which mode? I had to configure Panda Dome to use the proxy. Which version is your Panda Dome Essential of?

Of course, I know. Did you also have to use ProxHTTPSProxy for the activation of Panda Dome?

Forget about the Panda support! I reported the issue twice. The second report was quite detailed. No response so far. Not even an acknowledgement of receipt or the opening of a support ticket. Very disappointing! Although Panda Antivirus Free 21.01.00 is running on Windows XP better than the latest version, even this version seems to have problems. And once again, the culprit is the process PSANHost.exe which yesterday suddenly started to crash from time to time for whatever reason. I'm currently trying to determine the reason for these crashes. This PSANHost.exe is slowly getting on my nerves. Either I solve the problem or Panda Antivirus will be completely removed from my system. The Panda support seems to be non-existent.

My new beloved superhero, @autodidact : https://msfn.org/board/profile/398146-autodidact/content/ This most kind, generous and altruistic person is also a member on the videohelp.com forums, where he's been releasing Win7-compatible FFmpeg builds periodically; and here, he's doing the same for Vista/XP users; in some way, he's picked up the baton from Reino (whose very old, SSE-only, PC with XP died one year ago) ... As I said, it was by necessity ; but I don't think he's regretted it ...

FWIW, .NET FW 4.0 isn't a replacement for older .NET frameworks; 2.0/3.5/4.0 can co-exist on the same machine, and each one caters to applications targeting that specific version of .NET FW; i.e., if an app was built against 2.0, it needs 2.0 installed to run; likewise for newer apps built against 4.0... On Vista and later Windows versions, a newer 4.*.* version will overwrite a previously installed 4.*.* version of .NET FW, however this is NOT applicable to XP SP3, where only 4.0.x was made available; loyal XP users here can chime in to assist you, but from memory I recall than some feature/security updates for .NET FW 4.0 were made available at the time for XP SP3; unless the (recent) installer you linked to has those bundled ...

The two programs I use for this area of trouble, usually to un-associate a program I've accidentally used forgetting to uncheck the, annoyingly, Windows checked by default 'make default' tick box rather than what is described here as being the problem are:- https://defaultprogramseditor.com/ and https://www.softpedia.com/get/System/OS-Enhancements/Unassoc.shtml I was thinking that you could try to un-associate everything already associated with opening a .pdf then with that clean slate trying to associate the program wanted. I find it a bit unusual that a 'proper' PDF viewer like Adobe Reader, Sumatra or Foxit are not amongst the options as usually, arrogantly, Adobe will assign itself by default to open any .pdf file type. So even if you use something else you'd expect to see it in the list. Whether these programs will help in this case I do not know but they're useful tools to have particularly as they both work with XP and Win7.

jaclaz , I'm terribly sorry . I was talking about Uninterrupitble Power Supply , not the {awful} company UPS . In my opinion, all private companies like DHL Express and UPS are very bad with their own "rules". If you are talking about DHL POST of Germany , then I agree - it is much, much better . I only had one broken box from them . Got damaged somewhere in Leipzig. But the goods (to my surprise) arrived in one piece. EDIT : This is NOT because I don't like private property. I'm just stating the facts gathered from my friends , family and my personal encounters with these companies.

Oh , that's bad . I'm kinda gamer too . Are there any other alternatives ? (please not from kaspersky or the such) , thank you.

I told ya it was RAM . You need to remove all and test with only one module inserted. BTW , RAM testing tools are not good in my opinion. I had a funny case when the guy that was checking my faulty RAM at the store had 100% good test results and then he just couldn't boot into windows ! I also remember some similar case when my DDR2 RAM module no. 1 developed a faulty sector after a couple weeks of usage in a brand new PC . As for the second hand items , never use them in a PC where you do something important . People just do not know how to handle such items , just don't . Most never heard of static electricity and UPS.
