Is a 2004 antivirus program better than a 2003 version with the newest virus
definition updates?
Since your subject is av programs in general, and not NAV in
particular, I'll interpret your question. Note that most av products
don't go by yearly designations but by version numbers.
I think McAfee in particular points out and stresses which of its
versions are no longer supported. You can find the info at their web
site. There is always a danger in using old versions without finding
out whether or not the scan engine is still effective with the current
dat or sig files. Sometimes scanner redesigns/modifications make older
versions truly obsolete. But that doesn't necessarily mean that all
older versions and scan engines are obsolete.
So you have to ask your question specifically about a particular
antivirus product and version. Check their web site and/or contact
their sales or technical support.
