Hello all, My apologies if this is a tired & previously exhausted debate, but I was unable to identify any thread using search, so I am posting. As you may be aware, Nod32 v.4 is priced at several online retailers significantly below v.5. Obviously, they are in the process of shedding an older version, but sometimes those older versions have a lot of mileage left on them. I am assuming that v.4 will continue to be supported by the new defs and I'm thinking it may well have a 1-2 years of life left in it. I'm not aware of any performance value to be gained in current versions, so my question is why NOT buy v.4? Can someone advise on the benefits/disadvantages of purchasing multiple licenses of v.4 over v.5? Thanks in advance for your response and thoughts!
