I use a Mac for teaching my classes. There are a number of Windows systems from which there is a constant transfer of information, to and fro. When I plug in my USB flash drive in my mac it just shows the documents present in it. But when I connect the same flash drive to a windows system it shows that flash drive is infected with virus. Does my macbook have a virus? I have formatted my flash drive numerous times but the problem still remains.
When you erase/format a USB stick or other storage media in a Mac, the OS adds some hidden files like DStores or similar and EFI something. It appears that a PC/antivirus is saying those are viruses.
currently there are no Mac virus yet to be discovered in the wild, but from a Windows AV standpoint you are experiencing what is commonly referred to as a "False Positive'. A false positive commonly occurs when the Windows anti-virus product incorrectly identifies a file on the drive as suspicious or harmful because it can not identify correctly what that file is.
Is my Mac infected?
