I have been looking at the various posts for all the types of AV discussed in this forum. For some a basic AV is what they want and it suits them well - e.g. F Prot and perhaps Anti Vir. Other AV's are now coming with rootkit scanners (including Anti Vir), antispyware modules, HIPS modules, some type of sandboxing modules, HTTP scanners, e mail scanners etc. So my question is; are these add on's really required, do they make a huge difference in protecting your machine, are they are marketing ploy? Is this a phase to era where AV's will not really be AV's but a single product providing muliple layers of protection? Best wishes.
