LH outlines how easily malware can run on your computer simply by plugging in an infected USB device. This can be prevented however by disabling the AutoRun feature that's built into Windows.
For the more tech saavy out there (or those just willing to take risks) here's the change you can make to the Registry to disable AutoRun.
Open notepad and copy/paste the following into it:
REGEDIT4
[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\IniFileMapping\Autorun.inf]
@="@SYS:DoesNotExist"
After pasting, safe the file as
something.reg and after saving, double click the newly created file.
You will receive a prompt asking if you want to add the data to the registry, simply click yes to allow.
This hack disables any requests for the autorun.inf, which is where many virus laced USB devices store their malicious code.
If that seems too risky or difficult for you, read the article linked below for simpler options.
