|And you potentially open up new massive problems.|
Do not do the above unless it's a last resort. This opens your computer to every port directly to unsolicited incoming traffic, and can result on your machine being hacked in a matter of minutes.
Try like heck to use port forwarding and make exceptions in your software firewall first. If you must use DMZ, I would suggest the following:
Vigilantly patch your system.
At the very least, make sure the Windows Firewall is enabled. More preferably, use a better software firewall such as Kerio or Zonealarm, or others.
Unbind File and Print Sharing on your Network Connection Object in Windows.
If you have personal information on your computer, if you can, move it off to another computer.
Avoid if possible doing things with personal information on this computer, such as logging onto online banking sites, typing sensitive user names and passwords, etc.
I highly recommend NOT doing the DMZ solution!

Hats off & applause to rogues & evolution!
The ripple effect is too good not to mention.
If you’re not affected, you’re not paying attention!"
