I'm looking for a source of descriptions of 1990s to early 2000s malware; I have searched for a very long time yet found very little. I require information such as payload activation dates, files created, files deleted, and similar.
Edit: I've found a few sites that give vague descriptions, such as the following:
https://www.symantec.com/security_response/landing/azlisting.jsp?azid=W - has many malicious programs listed, and gives descriptions of a few, but they aren't enough to determine payloads or activation dates.
https://www.f-secure.com/en/web/labs_global/threat-descriptions - only has recent malware.
http://www.microsoft.com/security/portal/threat/Threats.aspx - has a very large number of malware programs listed, but almost all have extremely generic descriptions
In addition, I found one source that was closer to what I wanted, but it had descriptions for only a very small number of programs: http://www.viriipedia.com/index.php?CN=20&CIE=1
Where does one find this type of historical data?
