Websites no longer loading!

I’ve always used AVG before, and lately AVG themselves have been messing up so i though i’d try Avast.

After installing and opening Internet Explorer I find that some of the websites in my favourites no longer load?!

I know they all cant have their servers down, i even asked a friend to see if he could get it them and he can.

I’ve uninstalled Avast, even done a system restore to a couple days ago and reinstalled AVG. And yet these sites still arent loading!

All anime sites which include:

http://www.dattebayo.com/
http://www.maximum7.net/
http://www.narutofan.com/
http://www.onemanga.com/

Just to name a few. All these sites were working before I installed Avast and now they dont. Like I’ve said I’ve uninstalled Avast but they are still not loading.
Any ideas of what Avast could have done?

Only have windows firewall as well as the firewall on my router no Za or anything.

AVG seems to have become a pig to remove. Try the removal tool:

For a clean install of avast!:

Uninstall avast! Reboot.
Run the AVG removal tool. Reboot.
Reinstall avast!
