The Internet Archive has recently released The Malware Museum, a collection of old viruses and malware from the eighties and nineties.
The idea behind the "museum" is to experience what it was like to have your computer infected with a virus, back in the day when there was no internet and hardly any anti-virus software available.
The malware on this site is usually so old you need to use an emulator (such as DOSBox) and has been stripped from all malicious code, leaving only the on-screen messages intact.
By default, 7-Zip SFX (self-extracting executable) creation only has basic configuration options. With 7-Zip SFX Maker, you can expand those options with a whole lot more.
This piece of software allows the creation of customized SFX, taking 7z files as input. Things like changing the icon, captions, default extraction path and more, are all implemented. This makes 7-Zip SFX Maker a handy tool when you require a little more than a standard SFX but less than a fully-fledged installer.
