Is there an a free virus scanner and ad aware scanner available that can be put on a USB flash drive and used without having to install on a computer when you want to scan that computer. Eg if a computer has virus and there is concerns the virus scanner is not working properly, I want to plug in the USB drive and run the virus scanner on the USB drive.

Have you tried AVG by Grisoft, there's a free version that works pretty well. I can't honestly remember if it let's you run it from a flash drive - I think so though. But it did have a useful feature where you could download updates without having the program installed …

You can use ClamWin. Although it is not as good as the real time ones, but it can be put in the USB drive and taken anywhere for scanning.

May I suggest that you look at UBCD4Win (Ultimate boot CD for Windows) it gives you many more options than just a single virus scanner. Password hacks, hard drive utilities, registry editors and scanners, Backups and you can add additional drivers and software.
