This guide was intended for users with limited technical knowledge. If they knew how to use a Linux Live CD, they probably don't need a guide on how to install and scan with MalwareBytes. Eset does have an online scanner that you download, update, then run without actually installing it. I have used it on several occasions but, dislike it simply due to how long it actually takes for the whole process. Updating, scanning, then removal can take up to 45 minutes, depending on hardware and level of infection. Granted, it isn't a live CD but, it is an on demand scanner that isn't already installed, possibly eliminating it from being comprised by the malware.
