Yeah, I like Memorize and you can make it portable too. I added it to my Iron Key USB flash drive as part of my tool kit. You just have to make sure to run it once from your flash drive with write-mode enable to let it copy some additional files.
Also, last week I had the chance to play around with Redline. I like it except that you need .Net Framework version 4 or greater to use it on your Windows machine. Currently, it's very slow in analyzing memory dumps and it doesn't work well with Windows 7. But hey, it's new and I'm sure that Mandiant will improve it and make it better. I do recommend for beginners to take look at Redline and use it because it walks you through with explaination on quickly detecting suspicious or potentially malicious processes and etc.
Btw, Don, I can't thank you enough for the Iron Key flash drive. I can't live without it! Since I can unlock the Iron Key in read-mode only, it's perfect for incident response and malware forensic. You don't have to worry about your flash drive getting infected. I know it has been more than a year that I received my Iron Key, but I just wanted to say thanks again.
