How to prevent spread the virus when copying files from usb drives (without any anti-virus soft-wares). I think using command prompt to copying the files from usb which prevent the virus attacks. Is it true? Or any other way you know?

You can copy required files from usb few mouse clicks and just hold ctrl+alt+shift and insert usb drive into usb and after no autoplay will run. Open my Computer and dont double click or right click on the usb drive, if you clicked the virus will spread and go to the address bar and click the dropdown menu, copy the required files from usb drive to destination.

And here once check whether you are going to copy the files that which are original files because some viruses hide the original files and creates duplicate on the same name called .exe, for example there is folder called new folder and virus here hides the new folder and a duplicate exe file is created with the same icon and when you double click it will executes and infects your PC, so here once check before copying goto properties of that folder or file after see that whether it is in desired format or not and then copy the required files.

You can copy from dos aswell and just you need to the few commands, but I am not sure that this process prevents the virus attacks

Its a 16gb usb flash drive and I have used it in the past, but I deleted data and it still says that it has 15gb used and wont take anything more than 1gb. CAN SOMEONE PLEASE EXPLAIN WHATS HAPPENING?

Sol:- As the pendrive is 16gb, after deleting all the data it is still showing the 15 gb in use, which means a possibly virus file is in the USB drive.

 

You need to unhide the files. go to tools-> folder options->show all files.

Now the hidden files are shown and you can select them all and delete them.

If problem persists you need to format your usb drive and you format your pendrive using some format tools which can available on internet
