help i need to dremove a locked file which is a worm

[FULLMETAL039]

well we bought a second hand micro sd card from ebay. i was using it fine on osx no problems but when my brother put it on his pc there seems to be a worm on the card as his virus protection pops up. using my mac i am able to pinpoint the worm file but its a locked file and osx wont let me delet it or move it to the trash because its a locked file.

my question is how can i delet this file so my brother is able to use on his pc?

i am using OSX 10.6.1

thanks

hm i would simply suggest you format the card like a normal drive ,then the worm should be gone , only problem might be , even the worm will very likely not harm your osx , but could well be on your system somewhere so get a antivirus program that can scan your osx as you might spread the worm via emails ,eventually, if you use bootcamp and have a windows installed i could hide there
