Hi, I hope this is the right forum to post this. I recently used my usb on one of the school computers and they warned me that there is a trojan installed on the usb. Is there anyway that this autorun.inf trojan can affect Lion? From what I have read, it seems it's only a windows side of thing? I ran ClamXAV on my user name and didn't find any effected files so hopefully, it's ok. I am also reformatting my usb by using the secure erase in disk utility and hopefully it will get rid of it... does that work? Can anyone tell me if there is anything else I should check? Thanks!
