Disclaimer: There are a number of threads on this particular sub-forum regarding browsing security, spyware, etc., so hopefully the following isn't duplicated elsewhere. The above said, I've recently been experimenting a bit with virtualization, and thus far I am quite happy. More specifically, I've been trying out VMWare's free "player" software, along with the "browser appliance" (also free). I have been an avid Firefox fan up until this point (running a Windows platform PC), but have still found that spyware tends to slip through to some degree (according to my spyware scanners). It is frankly a pain to constantly be scanning my computer for viruses and spyware, so I decided to start looking around. I have played around a bit with various *nix variants in the past, but have never really had enough time to devote to truly "mastering" them as a daily use OS. I have also recently been poking around a bit into virtualization, because I have seriously been considering buying a Mac as my next general use comp. I managed to stumble across the VMWare "player" solution, have been using it for a few days, and have to say that it is very elegant. In short form, you launch the player, point it in the direction of the browser appliance file (directory), and it boots into Ubuntu Linux, then launches Firefox (an older version unfortunately, not 2.0). Performance has been mixed, definitely slower than running Firefox on my host OS, but I also possess an aging comp (P4 2.1 GHz, little under 1GB RAM, etc.). Based on my understanding thus far, the key point with this solution is that you can configure the appliance to reset each time you "turn off" the VMWare PC. Not just a reset of volatile memory, but instead a reset of the entire volume to the state it was in prior to the previous launch (i.e. it can be configured to never change, you can also configure it to save changes, useful for initially setting up your bookmarks and such). This essentially means that you can surf without worrying about spyware, viruses, etc. - anything that gets through should be gone the next time you boot the appliance. Also worth mentioning that I'm fairly certain that Ubuntu itself is far more secure than Windows. I'm interested to continue some discussion on this topic, particularly the experiences that other forum members have had with virtualization. At this point I'm interested to see what comes of the VMWare beta for MacOS, because I may indeed choose to go that route, rather than running Windows as host OS going forward. This is particularly relevant for a trading forum, given that most trading and quote platforms are currently only available for Windows.
