What can I do?
Turn off autoruns! Technically, you tell your windows computer not to run them.
What are Autoruns?
They are little hidden files ( named autorun.inf ) on your usb drive or CDs that run automatically when you insert them. Viruses insert themselves into this file.
Why are they there?
They autostart installation CDs or open a window for you. Viruses hijack the file.
If I turn them off, will it cause problems?
Not as big as autorun viruses! Turn them off! In the future when you insert a USB drive, you'll have to go through My Computer to open it.
Okay, how do I turn off autoruns?
Save this file NoAutoRun.reg to your desktop desktop (Windoze might change the name to NoAutoRun.txt .. stupid windows .. change it back to NoAutoRun.reg) and double click it. Say, yes to run it or whatever it asks.
You're done.
I have an infected usb-drive. What do I do?
Give it to your friend with a Mac computer and ask them to erase autorun.inf from the drive.
