In my opinion ESET make a serious mistake by eliminating the ability to create a "Rescue Disk" (or USB flash stick) with the NOD32 program. I ran into a piece of malware that compromised booting my system. In the past I could boot from a rescue disk, check for the latest definitions, scan, clean, etc. Now that activity is eliminated.
I ended up using a competitor's product that allowed me to boot from a stick and clean the malware. This is something ESET should put back in their product, or at least have the functionality on their website to download an image and create a bootable media.
