portable antivirus with a twist-any ideas?

[PSK]

hi.
so i am looking for a portable antivirus for a pendrive/external hard disk.
but heres the catch....it should be automatic (i mean it should not run only when the user selects it) and....it should provide protection in real time for the pendrive (not necessarily the pc but it should automatically protect the pendrive)

so in case someone tries to copy a bad file to the pendrive then it should repair the file or stop it from copying.

any ideas?
ps. thanks to jayclub...he made me wanna ask a question with his nice thread related to why we should ask questions in this forum

pps. i wonder how many others have thought about the same question.....hmm....

There are such antiviruses made by Avast, McAfee, Trustport but none are free. So, you can use vaccination to protect your antivirus .
For that use Panda USB Vaccine

or USB Defender

or you can encrypt your USB drive with USB Safeguard

Lol this will not give real time protection. Only on demand...

thanks for those names sujay...vaccination is the next best thing :P
but well...i was curious about something which can do heuristics in real time for the pen drive from the pen drive...so any other ideas you got?

ps. freewares only...i have been trying to avoid cracks and i cant afford to spend money on these not-necessary (but appreciated) luxuries.

I know of no portable AV that is real time, so I'd recommend USB immunization.
