Attention all pen derive users..
Still there are some viruses which are not easily detected by anti viruses like avast free version..
so to see them just do follows after scanning....
1. goto tool option of windows explorer
2. then folder option
3. view tab
4.uncheck the option "hide protected operating system files"
5.now you will see some unknown file (faded colour) in pen derive ..
delete them..
NOTE:- Don't use this method for hard disk since it's contains some important file which are hidden..but pen derive doesn't..
