Hey guys!

New to the forum here. absolutely loving it.

I had a couple of questions about how to prepare a flash drive with some emergency tools. I work as a retail tech now but want to start working up the ladder.

I have a couple of executables/software titles I want to put on a flash drive. The software I am planning on installing is MBAM, Spybot, TDSSKiller, cCleaner, ComboFix, GMER, and Avast (for boot time scans). I also have some cds (puppy linux, ubuntu, repair disks, UBCD, etc.)

now for my question. Is it safe enough to launch these executables on an infected machine? Or should I set it up to run from the flash drive? I have a bit of AV experience but have barely gotten started. Most techs seem to disable a few services, and then install. What do you guys think the best solution is?

Thanks!

Not sure what you mean with safe, but you run a considerable risk that the infected machine will infect your USB drive when you connect it, for example by copying malware + autorun instructions, or by infecting executables on your drive.

You could use a read-only USB stick to protect yourself, or a SD card like I explained here http://blog.didierstevens.com/2009/12/20/quickpost-read-only-usb-stick/
But be aware that the SD card's read-only switch is honored by the device driver, it is not an electrical switch connected to the circuitry of the SD card.
