Downloaded avast! on my Mac and now cannot connect to the Internet

Hi, I downloaded avast! to my Mac yesterday and shortly after, my Mac could not connect to the Internet anywhere. I have tried uninstalling avast! and ran a search for any remaining avast! files and deleted them, but still cannot connect to the Internet. I’m not positive that it’s due to avast! but I was hoping someone on here has experienced a similar issue or can direct me to a thread that addresses this issue. Right now I’m on my phone and it is pretty inconvenient to look for similar issues without being familiar with this forum. If anyone can find a solution for this issue for me, that would be great.

Avast for Mac forum section is here. http://forum.avast.com/index.php?board=5.0

Thanks!
