[clamav-users] detection of really old viruses?

[Marcel Giannelia (Felix)]

Most of the virus definitions in the cvd files don't seem to have dates
associated with them (at least that I could see with sigtool), so I
can't tell -- are older definitions ever dropped?

That is, will clamav always be able to detect viruses from, e.g., the
1990s, or are definitions for viruses that old eventually removed from
the database?
