Hello, I hope I' am posting this in the right area, since it relates to Malware removal, etc.
Anywho, I was wondering if there was a way someone could create their flash drive into a i guess "Mobile malware removal stick". By this I mean putting a few anti-virus programs on your flash drive and inserting it into a infected pc. I have read a few articles about it before and didnt think it could be done due to the risk, I think of your flash drive getting infected also. So if you happen to know if making a dedicated flash drive a "mobile malware removal stick" is possible, I would love a quick guide on how to do so.

You can do that. To keep the stick from being infected you create a folder called autorun.inf and put it on the root of your flash drive. Probably should also create one called desktop.ini too. Then add OTL, MBAM, Combofix, aswMBR, MBRCheck, and whatever else you like to use. (Virus Scan your usb drive whenever you bring it back to the good PC)

Another possibility is to create a boot usb. You put it in when the PC is off then boot off it and that keeps the virus from being active. Hiren's Boot CD is a collection of useful tools (His mini XP is a favorite of mine):

and he gives instructions on how to create a bootable USB:

This same method could be used with any of the rescue disks - a few examples:

Many thanks for your help! So when you say make a folder titled autorun.inf, and put it on the root of your flash drive, that means the other folder desktop.ini is going to be the sub-folder? Sorry if my questions are a bit newbie.

No you want both folders to be attached to the root.

Let's say the USB drive would be E:\ on your PC then you would want it to look like this when done:

E:\Autorun.inf
E:\desktop.ini
E:\Combofix.exe
...

You don't put anything in the folders Autorun.inf and desktop.ini. They are just there to keep malware from writing files of the same names to your USB drive. These files are used by malware to cause a USB to infect a computer. My installing folders of the same name we prevent the creation of these files.
