I was planning from switching from Symantec 2005 anti-virus to nod32. I downloaded the trial and it appears that my computer is actually using MORE memory than when I used Symantec. I know all the boards indicate it is "light", but doesn't seem to be the case on my machine. Symantec memory available: 481316 Nod32 memory available: 466960 Found: nod32krn using 19,324 nhlsrv using 1,964 npfmontor using 3,488 Don't know if the last two files are related to nod or not. Just wanted to know if the higher memory usage could be possible? Thanks.
