Hi all,
I recently purchased NOD32 and have been very impressed with its speed and low resource usage. I've followed Blackspear's recommended settings guide on the forum and have had only a few issues (trying to get NOD to ignore a certain file, which it classed as a trojan. The utility was from www.nirsoft.net, called Protected Storage PassView. Even after excluding it, on trying to run the app NOD immediately quarantined it.).
Yesterday I downloaded ABC Amber Text Converter (as well as 3 others) from www.processtext.com. I had purchased these a while ago but have not reinstalled it since my last XP clean install. The files are packed as zip files with a .exe installer. I went to extract them to my archive folder using Winrar. I started the extraction and there was a significant pause between each file as they were extracted - which took much longer than usual. After checking with Task Manager it seems to be the nod32krn.exe process which takes 70%-95% CPU time whilst the extraction takes place.
The pause and high CPU usage also occurs if you right-click > Properties on the setup file and also if you run the installed program.
After going through the settings in AMON, I have found turning off Advanced Heuristics solves the problem and the software starts normally and has no problems - and you can right-click > Properties with no pause.
The bit I do not understand is that the Advanced Heuristics option is in a section that says "Additional options on Create" - for new and modified files. Which, as I understand it, would mean the pause on extraction was to be expect if NOD32 can unpack the file but why should there be a pause on get the properties for the file or when running the installed app?
Does anyone here have the same pause on their system (just try downloading the demo of ABC Text Converter)?
Also as I'm typing this, I've tried to download their outlook converter which NOD32 has altered me as being infected with
probably unknown NewHeur_PE virus (I have submitted the file). The Text Converter has NO virus alerts but the software from this company seems to cause NOD32 slow downs.
Thanks for any help - or an explanation of why this happens with these files (has AH been updated recently?)

p.s. I also use AppDefend so I fairly certain the exe's are not changing each time I run them - or that the installed applications are changing in anyway.
