When I was running Vista, I would occasionally use an antivirus rescue disk as a “third opinion” scanner. (Malwarebytes Free was my second opinion scanner, and of course I always had a good first opinion antivirus with real-time protection.) I was thinking of recommending my former favorite to wither 3 in his present predicament, but unfortunately it appears that ESET SysRescue Live was terminated on September 29, 2023.
That’s too bad because it supported operating systems as far back as Windows 2000. I believe Bitdefender’s rescue disk was also discontinued years ago. I also believe you would have to install Avast to get their rescue disk. I never used theirs even when I had Avast installed because I wanted my third opinion to come from a different company than my first opinion.
I will always remember using MSE on Vista during 2015-2017 as the good old days: so much more relaxing than using third-party antivirus products that often created more problems than they solved. In defense of the idea of using MSE 4.4.304.0 on Vista, it has been argued that it doesn’t matter how old the MSE client is as long as Microsoft updates the engine because it is the engine that does the actual work. That is a good argument, assuming that the latest engine actually works in an old client running on an old OS. That is why I really wish you had visited AMTSO Security Features Check Tools - AMTSO to test MSE 4.4. Sorry for not posting a link when I first mentioned this idea: It was actually harder to find than I expected. My favorite test was for drive-by downloads. MSE does not have anti-phishing so don’t be discouraged by that test. If you see a green system tray notification from MSE and the test file goes to quarantine, then the engine is working. We could then say that MSE meets or exceeds the latest “better than nothing” security standard for Vista gurus. But if the engine cannot prevent the test file from being downloaded, then MSE is no better than no real-time protection at all.
MSE hasn’t been an option for Windows XP for several years. You might think this is only because there is no SHA-2 update for XP, but actually the first thing to go was the engine: Microsoft’s engine updates became incompatible with XP long before they were signed with SHA-2 exclusively. Are they still compatible with Vista? I dunno, you tell me!

Oh no: Have I become an overzealous Microsoft Security Essentials naysayer?Your comment on MSE is also a factor in not messing with Vista anymore. I guess I had some fun with it, but it's time to let it go.
