Having a USB pendrive is good for productivity because it can carry large files despites its small size. With capacity more than 8gb and fast write/copy speed, this invention has become one of the most needed computer devices for students, workers, teachers, and others to manage their digital files nowadays.
However, with the heavy usage of USB pendrive a major problem arises. Virus creators turn their attention towards this tiny device to exploit unsecured computers. Many viruses infect the pendrives and of course inclusive of the PC where it is plugged in which has Microsoft Windows operating system installed. It is made possible due to the compromised autorun.inf script file which automatically execute in company with viruses files whenever the device containing the file is plugged into Windows-based computer. Windows operating system does not disable autorun by default.
To counter this problem, there are several methods that one can use. First is to enable write protect on USB flash drive which is useful if you plan not to do any change to your USB flash drive. There’s also viruses and malware removal tool by sUBs which comes in handy. But today I’m going to cover about free standalone antivirus solution which consists of both prevention and cure approaches.

Will test that soft. In my part, I just disable my autorun.inf file in my usb drive.

Antivirus for a USB drive is a good idea. I think most people wouldn’t bother with this as they fear wasting space on their portable drive. If the filesize is low enough I think it would be great.
