Windows 7 x64 CryptSvc under Svchost uploading data

Well after some more thought I have some suggestions. I know nothing about AVG Firewall though. I've use most free Firewall's but AVG's isn't one of them!

Check that your router firewall is enabled. I cannot give specific instuctions but if you log into your router you might well find a setting to enable/ disable it. This is an entirely different firewall than the one you use on your computer.

When you've done that run the tests here and report any problems:

Run tests 1 to 5: PC Flank: Make sure you're protected on all sides.

Edit: Do not be tempted to purchase the recommended firewall if your results are not perfect!

Then run the test here:

Shields Up! - click Proceed then "All service ports"
