I did quite a bit of work on Antivirus/Security section. Unfortunately, the options for Vista have only dwindled over the course of 2021 and 2022 Maybe the community could help find new additions for this section?
SUMMARY OF CHANGES TO THE LIST FOR OCTOBER 2, 2022:
Removed Avast AntiTrack, as Windows Vista and earlier are no longer supported by the product.
Removed all Bullguard products, as Bullguard was purchased by Norton in 2021 and the products are no longer sold under the Bullguard brand name. As a result, Windows Vista is no longer supported by Bullguard.
Removed Comodo Cloud Antivirus, as it was discontinued and merged with Comodo Internet Security.
Removed Cybergenic Shade Sandbox as it now requires Windows 10 or later, and the last version for Vista appears to be unavailable.
Removed ONG status from Comodo Cloud Scanner and added version number of the final version, as the software has not been updated since 2010.
Removed ONG status from Comodo Antivirus for Servers, as the software has not been updated in at least a decade (since Server 2012 is listed as the latest supported version of Windows Server for the product).
Listed Comodo Free Antivirus & Comodo Internet Security v12.0.0.6870 as last version for Windows Vista (according to this support article).
Removed CryptoPrevent Anti-Malware entirely, as the latest version does NOT work on Windows Vista, and no documentation exists anywhere on the end of XP/Vista support, nor is the final version available anywhere from my findings.
Removed G-Data "Business Solutions" in favor of G Data Security Client, which continues to support Vista (and XP).
Renamed "HouseCall" entry to HouseCall Online Scanner, as that is the only HouseCall product to still support Windows Vista.
Removed Jetico Personal Firewall, as the software has not been updated since 2016 and appears to be abandoned.
Removed ONG status from KeePass; listed v1.38 as the last version for Windows Vista.
Removed Malwarebytes Anti-Rootkit & Malwarebytes Chameleon, as the products appear to have been merged with Malwarebytes Anti-Malware within the past few years, meaning they're no longer supported on Windows Vista.
Removed the information regarding Norton definition updates ending in 2021, as it appears that it continues to receive definition updates on Vista as of October 2022.
Listed OSArmor 1.6.0 as the last version for Windows Vista.
Removed NoVirusThanks Anti-AutoExec as it was discontinued at some point since it was added to the list.
Removed NoVirusThanks SysHardener & Registry Guard/Guard service as they're no longer supported on Windows Vista and the last versions are not available online anywhere from what I can find.
Removed Prey Anti-Theft as it no longer works on Vista due to missing functions and the last version appears to be unavailable (ResolveLocaleName error).
Removed RogueKiller Anti-Malware as it no longer works on Vista due to missing functions and the last version appears to be unavailable (K32GetModuleInformation error).

Removed SecureAPlus as it has been discontinued in favor of CatchPulse, which does not support Windows Vista.

Listed Vipre Antivirus v10.x as the last version for Windows Vista.
Removed Webroot as the last version for Windows Vista cannot be found online and is not documented anywhere. The software now requires Windows 7 SP1 or later, according to the Webroot website. No trial versions are available for testing either from my findings.
Fixed broken download link for Enhanced Mitigation Experience Toolkit v5.52.
