Portable Firefox

I could have done with Portable Firefox on Sunday when round a friends house and got the "while you are here" request. Turns out that they can connect to the internet, receive and send emails ok but the web browser wouldn't work. After running a quick check for proxy settings etc it was obvious that some sort of internal dns to the browser wasn't working. A quick look in the installed programs and they had messenger plus installed. One uninstall and a reboot later, and the machine was functioning as intended. (Note to the messenger plus defenders - Yes they should have read the "optional" requirements - No you can't expect a 9 year old to understand the implications of installing adware "sponsered" software. To the messenger plus attackers, yes the software is actually pretty good - not essential and yes you can read the instructions.....sometimes)
Now the browser was fixed I was able to download an run adaware and fix the 130+ files it found. Hopefully a portable firefox on usb key will help to have a clean, uninfected browser (or there is Offbyone browserinstead that would do the same thing.
