After doing a fair amount of due diligence I have narrowed my new AV choice to the following. KAV Professional NOD 32 Extendia AVK Pro KAV Pro due to the high reviews and favorable comments found here and other places. It is the most expensive of my final 3 choices...but the dollars aren't a big deal. Seems to place in the top tier of any AV tests I have found available on the internet...except for about.com who placed it 7th or 8th I think. NOD 32 primarily due to its attractive price and the strong support and following found here at Wilders. Attractively priced and apparently it is light on system resources. From what I can read, it appears to do very well in certain AV tests and in others not quite so well. I'm sure there are reasons but I'm not an authority on such things. I can't imagine all the guys/gals here liking it as much as they do if it were only an average or above average AV though. Extendia AVK Pro only because at $29 it's too tempting not to include it for what you get for the money. Apparently it uses the KAV and RAV scan engines and updates itself daily. Also appears to be very much if not the same as GSoft's AVK Pro...although that product uses the KAV engine and I think one by BD? Maybe Extendia is simply the American marketing effort of the original product? No clue...but the price is a bit less and the daily updates are included in the price unlike the original AVK version which charges for the daily update feature. I have been a user of NAV and still have over 200 days left on my subscription...but a demo version of KAV found 5 viruses on my computer that NAV apparently couldn't...and I have NAV scheduled to run 3 scans a week (which it has been doing for the last couple of years) and my NAV updates are all current. I was a bit disappointed to say the least. I know that such choices are a personal matter and preference...but since I have narrowed it down to 3, I figured that some wise counsel is in order. Finally...I am not opposed to buying 2 of the above mentioned products if that is the best way to go. If so, please advise which 2. Thanks.
