I just finished my trial run of NOD32 and while I think that their signature updates are probably excellent, and it allows for many configurations, I felt it slowed down my computer experience considerably. I spend about 8-10 hours a day on the computer and the 'net, and very often I would find NOD32 slowing me to a crawl. When I installed new programs or downloaded files, I would watch NOD32 scan every little temp file and practically freeze the keyboard. I'm into computer safety, and I certainly didn't want to take the advice of some and uncheck the "scan all files" feature. In addition, I found that any time I opened a program (clicked on exe), there would be a several second hangtime. A reason could be that NOD32 doesn't interact well with Zone Alarm or some of my other security programs, but I haven't experienced this with Avira or Avast. Since I don't use Outlook, I don't need the EMON module, and the DMON shell just does what other AV programs do normally. Right now, my task manager indicates NOD32 is using 22 mg of ram, and Process Explorer indicates it's using 85 mg of virtual memory. While I respect the opinions of AV-comparatives.org, and think that NOD32 is a nice little AV program, I don't think it's currently worth $39. Considering that last week, some retailers had Kaspersky for free after rebate, Norton and McAfee can also be obtained free AR, Avira Premium is $26, and AVG, Avast, and Bitdefender are free, I'm going to try one of the latter. Perhaps I can even get a competitive upgrade program for free AR. Obviously, McAfee is a system hog and Norton seems to take over one's computer (although it's reviews are getting much better). I can't use Norton 2007 because I'm still on Windows 2000 Pro. That leaves me with Avira free or Premium, AVG or Avast. I always liked the bootscan feature of Avast and its email shield. For the time being, with a good HOSTS file, IE-Spyad, Zone Alarm Pro, a router, Spyware Terminator free and Win Patrol free, Avast or AVG with Bitdefender as an on demand backup, and greater use of Firefox with less of IE, my computer should be secure. When NOD32 gets a greater share of the market, reduces the price and fine tunes the program, I'll take another look at it.
