I don't remember exact count but I have over 100,000 files on computer that Norton 2001 used to scan in about 25 to 40 minutes. (Don't remember exact time). I first ran Eset trial a week or so ago, and don't remember how long it took. I think an hour or less, but am not sure. Ran the on demand scanner last night and it was still going at 1 hour 10 minutes, which seems excessive. It may be my imagination but it seems to slow down when scanning Open Office. It seemed to still be scanning that program when I stopped it. I am running this on a Compaq 6320 with AMD Athlon XP 2000+ 1.67GHz, with 256 MB DDR SDRAM, and an older version of free Zone alarm (6.0.633.003). Norton used to run okay. I like the Eset since it picked up a few things Norton missed, but this long scan time is a problem. It seems a little slow whether I run the "in depth" scan or the "on demand" scan. While the scan last night was running, there was an Eset NOD block on my bottom toolbar indicating 19%, which didn't seem to change for 1/2 hour or more. I am guessing that means the scan was 19% complete. Does anyone have some ideas/ advice? Also, how long should the average scan take? I know all systems different, but is 30 min or 45 min a rough typical figure or what?
