COMPUCILINA offers >protection agaist actual and future viruses. Truly interesting, if this is 100% true - but I doubt it. It is easy to add code to programs and boot sectors which will detect infection by 98% of currently known viruses - all the 400 or so known variants, other than a few "stealth" viruses. Adding code which PREVENTS something from being infected is an entirely different story - what if the computer is booted from a floppy and some infected program run ? No additions to other programs, no matter how sophisticated could prevent the programs from being infected. The additional code MIGHT detect the infection, but as I said before, detection and prevention are two different things. - -frisk Fridrik Skulason University of Iceland | Technical Editor of the Virus Bulletin (UK) | Reserved for future expansion E-Mail: frisk@rhi.hi.is Fax: 354-1-28801 | Brought to you by Super Global Mega Corp .com
