Nissan.exe and taskman registry entry

[MiLan]

hello guys,

Every time i insert usb flash drive websites like mainstories.com, bizrumours.com gets open automatically. After the scan MalwareBytes shows two infections Nissan.exe and taskman registry entry. After deleting those infections everything goes fine but, problem starts when i attach my usb drive.

Avira (updated) found 457 infections in flash drive. I thought USB was clean then, but it (website opening etc) started when i attached drive next time. Now i am sure that something is wrong in USB drive.

How do i clean my USB drive?????

below is the log file.
