I doubt there are any viruses that save themselves to flashdrives. Viruses are targeted to your harddrive and windows files. So you don't need an antivirus for your flash drive. (they probably don't even make any)

If you use your flash drive on a computer that has infected files and you copy these files to your flash drive, then ofcourse your computer can get infected with viruses or trojans.

Almost all antivirus software can be made to scan a specific drive or folder for viruses. If you make it a habit to scan your flash drive before you transfer or open files from it, the chances of you getting viruses can be reduced drastically.

Two antiviruses I recommend are

Clamwin

and AVG

These are free software. Clamwin has high detection rate, however it does not have onaccess scanner. This means that it will not intercept the file automatically, You have to ask it to scan before you open/copy the file. AVG has on access scanning however the detection rate is not as good as clamwin.

If you have your own favorite scanner, make it a habbit to scan your removable drive before you access it. Also never install Two antivirus packages at once, remove the old one before you try a new one.
