Just signing in to verify that this method worked for me too. Thanks!
OS: Windows 7 Home Premium v6.1 (build 7600)
Firewall: ZA Free 9.1.007.002
AV: Avast 100412-1
Applications: Mostly open-source, no MS suites like Office, Studio, etc.
That combo of Windows, AV, Firewall, and open-source apps is working really well so far.
Hope this info is useful,
