ITunes cannot connect to network

Question

I know other people are having connection issues, but I don't know if mine is the same problem. I've already had proxy connection issues with Firefox, which happened right after AVG quarantined a virus...I'm thinking that messed with my proxy settings. I fixed it on Firefox by changing a setting but now iTunes is not connecting. I'm getting a "network connection timed out" error when trying to connect to the Store and when I try checking for updates (I don't have the latest version of itunes) it says "The iTunes update server could not be contacted."
I've seen the help page entitled "iTunes for Windows: can't access the Internet if proxy settings are incorrect" but I don't understand the last few instructions. I don't know anything about this kind of stuff, so feel free to explain it to me like I'm an idiot.
I ran a Network Connectivity Test under Diagnostics and the results are thus:

Help, anyone?

Answer 1

Nevermind, I fixed it! If anyone is having the same problem, I had to go into Internet Explorer > Tools > Internet Options > Advanced > Reset Internet Explorer Setting. Then I restarted IE and restarted iTunes and problem solved!
