Are there anti-virus packages which check zipped files?
An increasing number of packages seem to support checking .ZIP and other compression formats on the fly. DSAVTK, AVP and NAV 3.0/NAV95 support some formats. The number of formats supported may become as big a selling point as the total number of viruses detected, but for most of us it’s only really an issue if we do a lot of scanning of CDs, for instance. Even then, it becomes urgent only if you unpack the archive and want to run programs. Compilers of CDs, however, are not entitled to use this as an excuse for not scanning their collections.
