but it’s incredible, avast is so fast , it did not slowdown my slow machine a P3 500 256 mb of ram

VLK , how can avast be so fast? i notice avast resident shield is more fast then nod32!
VLK which machine avast can slowdown ?!? 486

Well, it certainly depends on what you are doing; if you’re running some apps opening a big number of files, you may notice a slowdown… but otherwise, I don’t think we have any detailed “benchmarks”.

but the resident protection & on deman scanner have the same engine?

Both resident scanner and on demand scanner use only the one engine which is in user mode. As Igor noticed, I think we don’t have any detailed benchmarks of other antivirus products and we aren’t going to do that. We still improve r-scanner’s features to bring you the faster driver 8).
