Heavy CPU load when scanning.

I don't remember seeing this before. I just started scanning my pc and noticed my CPU usage was 100% for more than 5 minutes. Then it varied widely and then stayed between 90 & 100%.
Quit the scan for now.
Is this normal or could I have done something wrong when I installed and setup to BS's settings?
Thanks,
J.

 

I also noticed that once. It was kind of around 90 - 100%. Very annoying.

Perhaps there could be 2 or 3 levels of advanced heuristics in the future - one with worser detection capabilities and smaller impact on CPU and one with as best detection capabilities as possible but with a higher impact on CPU (current level).

 

When I scan (with everything enabled) it jumps back & forth between 25-80%.
Your issue could be hardware related or the buggy Vista OS.

 

It's pretty normal that an in-depth emulation of complex runtime packed files takes CPU time. What could be done to mitigate the CPU load is to let the user choose between a better detection and lower CPU load when scanning such complex files.

 

You can change the priority for NOD32.exe in Windows Task Manager/Processes. Right click on the process and Set priority to low.
