Okay, I'm looking for some enlightenment here. Two years ago, MKS_Vir and ArcaVir used the same engine. Does this stand true today as well? MKS_Vir offers English users a means to purchase the program, but is the support offered in English? As far as detection rates are concerned, I feel it (ArcaVir) is improving somewhat, as I have made a few strange observations about the product. So, is there anyone here who can comment on the *latest* versions of both these products (mikesu...would be nice if you could comment )?
