@druout1944 Have you tried to whitelist the *.exe files listed up here in your firewall and antivirus software ?
Because it worked for some, me included... and now it's been about one week since I last played online...

Though I agree that it is really annoying to have to do this kind of **** almost every time ^^

@pronabeshstark Ok,
The procedure will probably differ a little depending on your firewall but the overall idea should be similar.

Open Comodo, then go to "general functions", to "Applications to unlock" then select the applications (*.exe) that you want to unlock.
I can't be much more precise since it depends on the firewall you use.

@ashdator Thanks bro ! it helped me too, though I did it with Comodo firewall since I have this one
And it happened after the latest update
