It "was" no filter,
1. I'm using Comodo IS.
2. When Comodo IS. was working and I wanted to switch on CoD4-mp antivirus blocked it and computer stopped working.
3. I switched of Comodo IS... CoD4-MP still doesn't work.
4. I change options at windows firewall... CoD4-MP still doesn't work.
5. Punkbuster is updated, game has the latest patch. CoD-MP still doesn't work.
6. Looks like it was no patch, no update on PB, no game fault, no windows firewall.(my pc was “up to date” all the time, during this time.
7. I’ve found out that Comodo IS was the problem, because even if comodos FireWall is switched off it still blocks some files, so I had to mark those files as “my own safety files”.
8. On the other hand ,I added to safety files everything connected to CoD4.
9. Everything was updated, just in case.
10. There is another problem with PB, I'm getting kicked all the time from dedicated serwers. But a lot of ppl have problem with that so it's not a problem to find topic how to repair it.
I hope it help some other ppl in future,
thank you for help anyway.
omt, It would be great if admin, or mod correct my mistakes in english in steps.
