Hi Yance,

Are you sure this is a problem with avast? If you disable avast do the games work?
I just checked their website, and it seems a lot of the servers that run their games are not working - this is not an avast issue, but a problem with their website.

For example:

ping ge.lytogame.com

I think perhaps that this is not actually an avast issue, but simply that the games you are trying to play no longer work.

The only ones that worked for me were Requiem and Avalon.
