They are all showing, Judy - look more closely

That rules out any sort of false-positive.
Frankly, MBA-M should remove this, so something is restoring it: either the drive is infected or you have an infected pen drive(s).

There are a number of different ways to attack this - I'm sure Judy or tiger86 can help you on that front.

Hey sorry I haven't posted in a while. I did some quick research. Your log is very, well bad. You appear to be confickered majorly. If the conficker virus doesn't stop you from going to microsofts support page please follow the link http://support.microsoft.com/kb/962007 also on that page to see if your clean of conficker theres a link to http://safety.live.com and here is the Manual... yes a manual on removing conficker http://support.microsoft.com/kb/962007#Manualsteps
I hope that is helpful.
