If you allready noticed maybe, when you open the ingame browser, you get a window wich trys you to redirect to the dri clan server.
You should not visit that server, its possible you get a virus from them, they wanna destroy the last existence of ET.
To prefent this redirecting, install the etlegacy client from here ->
https://www.etlegacy.com/ET:Legacy have its own masterserver and fixed such problems.
If you wanna keep your old standart ET i advise you to add this ip´s ->
63.141.227.162
35.231.148.156
208.167.247.135
to your firewall, block incoming and outgoing traffic to all ports.
This is just a temporary fix. Till that guy changes the ip.
if you use windows firewall only, you can run this script:
extract the file to anywhere. Start the script with rightclick and run as admin.
I post
other solutions imedially when i know more. Of course you can post solutions too. Thanks.
Have a good fight. Cya ingame.
