Yes, I know that Windows XP SP3 and Windows 7 SP1 have been end-of-life for a long time, but in the wild they are still being used so here is for posterity:

Nice memories of the TBAV/ThunderByte Anti-Virus story.
Together with Jeroen Smulders, I was sort of on the sideline in the early days as we both were at the university had access to FidoNet (I as host, other Jeroen as point), Internet, mailing lists and newsgroups.
I used it because it was the fastest Virus Scanner around and a need when scanning all incoming FidoNet data for viruses (I had seen at university what damage a spread could do).
Some VIRUS-L, comp.virus and book links from that past:

I feel old, because I vividly remember the PCX (1985) graphics file format: it was the defacto standard under DOS.
TIFF (1986) was slightly younger, and came from the scanner background resulting in very large files though unlike PCX (which had lossless compression), TIFF supported both lossless and lossy compression.
On Windows and OS/2, you had BMP (1985, lossless initially only black and white).
All three suffered from the same problems: different implementations causing all sorts of compatibility problems
Those were the reason for the implementation of newer file formats for graphics like JPG (1992, lossy) and PNG (1996, lossless).

Before Firebird version 1.0 got released, a gaping security hole that InterBase introduced in 1994 before InterBase 6.0 (mostly written in C) got open sourced in 2000 was detected by the team that frantically tried the Firebird fork to first get building on various platforms, then released.
It had a maximum CVSS score of 10.0 because it could access the security database in read/write mode, thereby allowing adding users with SYSDBA privileges.
The detection is now about 25 years ago; on 20260109 the publication (by IBPhoenix) of the bug will be 25 years ago too.
So below are some links, including the original InterBase 6 source which was hard to find as the attachments of the original release links had not been archived in the Wayback Machine.
But first some of the code parts, which also shows the source file I did find back:

With the permission of Adobe Systems Inc., the Computer History Museum is pleased to make available, for non-commercial use, the source code to the 1990 version 1.0.1 of Photoshop. All the code is here with the exception of the MacApp applications library that was licensed from Apple. There are 179 files in the zipped folder, comprising about 128,000 lines of mostly uncommented but well-structured code. By line count, about 75% of the code is in Pascal, about 15% is in 68000 assembler language, and the rest is data of various sorts.

This is for earliest compact Apple Macintosh systems predating the introduction ADB (Apple Desktop Bus) on Macintosh SE and Apple Macintosh II (and Apple IIgs which technically is not a Macintosh):

Before continuing to an even more impressive keyboard and mouse interfacing project below (basically many kinds of modern keyboard, mice and gamepads to many retro computers) that I found thanks to doing some more research after finding the above one, lets summarise where the above one is still useful for:

Karateka (which appeared way before the even more famous Prince of Persia which appeared 5 years later) memories of the past, for which I totally agree with the conclusion: the game on Apple ][ was way better:
[Wayback/Archive] πΈπππ₯π ππͺ ππππ€πππππΎ on Twitter: “@textfiles Jordan’s opinion on the IBM version”
JULY 31, 1986
Just looked at the “final” version of PC Karateka. It seemed OK, I guessed, except for overall sluggishness, frequent disk accesses, and a few minor graphics glitches. Then I booted up the Apple version to compare… and it was so smooth, it made me want to cry.
The PC version is maybe 50% of what it should be. I can’t even tell these guys s what to fix… it’s a million little things, and they’re just not up to the hassle. That kind of attention to detail is why the Apple version took me two years. This version is probably the best I’ll ever get out of them.
You can play the PC version online atΒ [Wayback/Archive] Karateka IBM Version 1986-01-30 (1986-02-04) (ID 0873) : Jordan Mechner : Free Download, Borrow, and Streaming : Internet Archive
Internal Alpha version (1986-01-30) of the IBM port of Karateka by Jordan Mechner.
It was ported to many platforms, and there was a great documentary too. So there are more YouTube links below than [Wayback/Archive] Karateka IBM PC Model 5150 Longplay – YouTube which has this great description:
