In general, when we need to format a pen drive or hard disk drive then we open My Computer Window. Then select the drive and right click on it. Then we can format it.
But when pen drive is affected by virus, then the task gets some difficulties! Don't worry. Because in this post I am gonna show you how to format a virus affected USB Flash Drive.
Make sure your computer is secured with a strong and reliable security software. I prefer Microsoft Security Essential. Then scan your flash drive with it. And try to format it.
If you're fail to format it. Then follow another method. At first, make a right click on My Computer from your desktop. Then select the manage option. Now at the left panel you will find an option named Disk Management. Click on it and you will see all of your disk drives listed here. Now you will be able to format any drive you need. Right click on them and hit on format.
